Abstract:

The use of heterogenization as a method for achieving clean synthesis is discussed. The chemical modification of mesoporous solids can be used to make a range of catalysts, including solid acids and bases, and stable metal complexes for selective oxidations and other reactions. By avoiding an aqueous quench stage in the separation, the heterogenization of catalysts and reagents can lead to substantial reductions in waste produced in organic chemical manufacturing processes.

Abstract:

The natural beauty and purity of our planet has been contaminated deeply due to human selfish activities such as pollution, improper waste management, and various industrial and commercial discharges of untreated toxic by-products into the lap of nature. The collective impact of these hazardous suspensions into the natural habitat is very deadly. Challenges due to human activity on the environment have become ubiquitous. The chemical industry has a major role in human evolution and, predictably, opened gates of increased risk of pollution if the production is not done sustainably. In these circumstances, the notion of Green Chemistry has been identified as the efficient medium of synthesis of chemicals and procedures to eradicate the toxic production of harmful substances. Principles of Green Chemistry guide the scientist in their hunt towards chemical synthesis which requires the use of solvents. These solvents contaminate our air, water, land and surrounding due to its toxic properties. Even though sufficient precautions are taken for proper disposal of these solvents but it is difficult to be recycled. In order to preserve our future and coming generation from the adverse impacts associated with solvents it is very important to find alternative of this which will be easy to use, reusable and also eco-friendly. Solvents are used daily in various industrial processes as reaction medium, as diluters, and in separation procedures. As reaction medium, the role of solvent is to bring catalysts and reactants together and to release heat thus affecting activity and selectivity. The proper selection of the solvent considering its biological, physical and chemical properties is very necessary for product separation, environmental, safety handling and economic factors. Green solvents are the boon in this context. They are not only environmentally benign but also cost effective. The biggest challenge faced by the chemists is adaptation of methods and selection of solvents during chemical synthesis which will give negligible waste product and will remain human and nature friendly. During designing compounds for a particular reaction it is difficult to give assurance regarding the toxicity and biodegradability of the method. Chemists are still far away from predicting the various chemical and biological effects of the compounds on the back of the envelope. To achieve that point is formidable task but it will definitely act as inspiration for the coming generation of chemists. The green solvents are undoubtedly a far better approach to eliminate the negative impacts and aftermath of any chemical synthesis on the environment. Our study in this review covers an overview of green solvents, their role in safer chemical synthesis with reference to some of the important green solvents and their detail summarization.

Abstract:

Industrial research, including pharmaceutical research, is increasingly using liquid chromatography techniques. This involves the production of large quantities of hazardous and toxic organic waste. Therefore, it is essential at this point to focus interest on solutions proposed by so-called “green chemistry”. One such solution is the search for new methods or the use of new materials that will reduce waste. One of the most promising ideas is to perform chromatographic separation using pure water, without organic solvents, as a mobile phase. Such an approach requires novel stationary phases or specific chromatographic conditions, such as an elevated separation temperature. The following review paper aims to gather information on stationary phases used for separation under purely aqueous conditions at various temperatures.

Abstract:

Technological progress has made chemistry assume a role of primary importance in our daily life. However, the worsening of the level of environmental pollution is increasingly leading to the realization of more eco-friendly chemical processes due to the advent of green chemistry. The challenge of green chemistry is to produce more and better while consuming and rejecting less. It represents a profitable approach to address environmental problems and the new demands of industrial competitiveness. The concept of green chemistry finds application in several material syntheses such as organic, inorganic, and coordination materials and nanomaterials. One of the different goals pursued in the field of materials science is the application of GC for producing sustainable green polymers and membranes. In this context, extremely relevant is the application of green chemistry in the production of imprinted materials by means of its combination with molecular imprinting technology. Referring to this issue, in the present review, the application of the concept of green chemistry in the production of polymeric materials is discussed. In addition, the principles of green molecular imprinting as well as their application in developing greenificated, imprinted polymers and membranes are presented. In particular, green actions (e.g., the use of harmless chemicals, natural polymers, ultrasound-assisted synthesis and extraction, supercritical CO2, etc.) characterizing the imprinting and the post-imprinting process for producing green molecularly imprinted membranes are highlighted.

Abstract:

The introduction of the dimension of green chemistry into the assessment of analytical methods should be a natural development trend in chemistry and should coincide with its general policy. Some of the principles of green chemistry - such as prevention of waste generation; safer solvents and auxiliaries; design for energy efficiency; safer chemistry to minimize the potential of chemical accidents; development of instrumental methods - are directly related to analytical chemistry.Analytical chemistry is considered to be a small-scale activity, but this is not always true in the case of controlling and monitoring laboratories whose number of runs performed is high. This makes an analytical laboratory comparable with the fine chemicals or pharmaceutical industry. The use of instrumental methods instead of wet chemistry, automation, and minimization is a new trend in analytical chemistry, making this branch of chemistry more sustainable. In this study, widespread separation methods are considered and an attempt is made to characterize them against the above-mentioned principles. Special attention is given to capillary electrophoresis (CE), which provides a very good opportunity to improve analytical chemistry by replacing many chromatographic methods that consume large volumes of solvents. The choice of different solvents and micronization in analytical chemistry is also discussed.

Abstract:

Traditional sample preparation requires substantial resources and time, both adversely affecting the economical and ecological accounts of an analytical workflow. To address the dearth of greenness, this work used field-enhanced and electrokinetic sample injection from capillary electrophoresis (CE) for off-line sample preparation. This approach, referred to as electrophoretic concentration (EC) and simultaneous EC and separation (SECS), relies on the use of an electric field to transfer charged analytes from a mL-volume of aqueous sample to 20 μL of acceptor electrolyte immobilised in a micropipette. The use of a conductive hydrogel to facilitate a zero net-flow inside a fused silica capillary is described and then explored for EC of charged analytes. The hydrogel was crucial to the success of EC, because it supported voltage application and retained the acceptor electrolyte in the micropipette. Anionic dyes and pollutants from drinking water as well as cationic drugs from wastewater were concentrated in less than 50 min and sensitive analysis by CE was achieved. The EC setup was then modified for SECS and implemented on an eight channel device to increase the sample throughput. Herbicides fortified in river water and beer samples were used to study SECS in combination with chromatographic and electrophoretic separation employing UV and mass spectrometric detection. Analyte enrichments of up to a factor of 337 in less than 45 min were achieved which enabled low ng/mL detection. Compared to solid-phase extraction, SECS reduced the sample preparation time by 94% and resource consumption by 99%. EC and SECS in combination with stacking-CE showed potential for trace analysis and all the SECS and EC acceptor electrolytes were directly compatible for analytical separation without the need for time-consuming steps. EC and SECS were organic solvent-free, rapid and simple sample preparations which were complying with the principles of Green Analytical Chemistry.

Abstract:

Abstract: The aim of this research is to fabricate thin-film composite (TFC) membranes using a synthetic derivative of plant-based phenols, as a non-toxic building block for interfacial polymerization. Classical interfacially polymerized composite membranes are heavily integrated in reverse osmosis and nanofiltration applications for water and wastewater treatment and most recently for chemical and pharmaceutical industries. Implementing sustainable practices in membrane fabrication by exploiting greener alternatives to conventional chemicals can directly reduce hazardous waste and ultimately lower the global energy and environmental burdens. In this study, allyl gallate was chosen as a monomer to form selective thin films by the interfacial reaction with trimesoyl chloride on top of an asymmetrically porous polyacrylonitrile support. The advantage of the unreacted allyl groups is that they can be in the future used as post-functionalization sites. The highly volatile organic phase solvents were additionally replaced by an isoparaffinic fluid, commercially known as Isopar G. The chemical composition and morphology of the membrane was evaluated using solid-state 13C NMR, FTIR, and SEM. The optimized membrane resulted in a permeance of 12±2 and 48±14 L m-2 h-1 bar-1 for respectively pure water and methanol with a rejection in the nanofiltration range.

Abstract:

The processes of production in chemical-related industries often rely on the use of volatile organic solvents, normally generating large amounts of hazardous wastes. During the past decades, major efforts have been done to transform chemical processes included in the principles of Green Chemistry, Sustainability and, more recently, Circular Economy. This thesis intends to work on two important challenges of pharmaceutical industry, namely the valorization of pharmaceutical wastes and the separation of enantiomers resorting on the application of alternative solvents, in particular, ionic liquids (ILs) and deep eutectic solvents (DES). Motivated by circular economy and searching for a new strategy to the currently proposed (i.e., incineration), novel aproaches to valorize wastes of domestic origin (unspent and/or outdated medicines) are proposed. Since circa 90 % of the active ingredients in an outdated medicine are still in their active form, in this work, the recovery of valuable active drugs from pharmaceutical wastes using IL-mediated extraction processes is proposed. The processes of extraction and separation of drugs from pharmaceutical wastes require an initial step of solid-liquid extraction, which was designed in this work by the use of different ILs, well-recognized by their solvency power of ILs for a large plethora of compounds/biomolecules. The separation stage of the extracted active ingredients was also investigated by the application of IL-based aqueous biphasic systems (ABS) or IL-based three-phase partitioning (TPP). In the end, the isolation of the active ingredients was accomplished by the addition of anti-solvents properly selected. The wide applicability of the proposed ABS-based technology was evidenced by the recovery of several model active pharmaceutical ingredients (three non-steroidal anti-inflammatory drugs and one antidepressant). The challenge of dealing with racemic mixtures and the differentiated biological activities that enantiomers generally present is investigated in this thesis. The most common two approaches to obtain pure enantiomers are the asymmetric synthesis and the separation of racemates. Although being considered the most powerful approach, the asymmetric synthesis is limited by the high costs and complexity of the processes. In turn, the separation of racemates is more flexible, cheaper and simpler. Under this scenario, it is here proposed the use of ABS composed of chiral ILs (CILs) as an alternative to enantioseparation. Two groups of CILs, i.e., those bearing chiral cations and those containing chiral anions were synthesized and applied to enantioseparation. After the characterization of the ABS phase diagrams (CIL + salt, CIL + polymer) it was possible to evaluate their enantioselectivity on the separation of racemic mandelic acid, here used as model racemic compound. In a second approach, deep eutectic solvents (DES) were envisaged as potential chiral solvents by the study of chirality impact on the solid-liquid equilibrium diagram.
Os processos de produção da indústria química e relacionadas baseiam-se no uso de solventes orgânicos voláteis, gerando quantidades elevadas de resíduos perigosos. Durante as últimas décadas, têm sido realizados inúmeros esforços para modificar os processos químicos tendo em conta os princípios da Química Verde, Sustentabilidade e, mais recentemente, da Economia Circular. Esta tese pretende solucionar dois importantes desafios da indústria farmacêutica, a valorização de resíduos farmacêuticos e a separação de enantiómeros, utilizando duas classes de solventes alternativos, em particular, os Líquidos Iónicos (LIs) e os Solventes Eutéticos Profundos. No âmbito do conceito da Economia Circular e na procura de uma alternativa à estratégia atualmente utilizada (i.e., incineração), novas estratégias para a valorização de resíduos farmacêuticos domésticos (medicamentos não usados e/ou fora da validade) são apresentadas. Dado que cerca de 90 % dos princípios ativos num medicamento fora do prazo permanecem no seu estado ativo, é aqui sugerida a recuperação de fármacos a partir de resíduos farmacêuticos utilizando processos de extração com LIs. Os processos de separação dos princípios ativos de fármacos a partir destes resíduos requerem uma etapa inicial de extração sólido-líquido, desenvolvida neste trabalho pelo uso de diferentes LIs, reconhecidos pelo seu elevado poder solvente para uma larga gama de compostos/biomoléculas. A etapa de separação dos princípios ativos após a sua recuperação dos resíduos foi estudada pela aplicação de sistemas aquosos bifásicos (SABs) e sistemas de partição de três fases aquosas igualmente constituídos por LIs. Por sua vez, a etapa de isolamento dos princípios ativos após a sua separação foi desenvolvida pela adição de anti-solventes devidamente selecionados. O desafio de lidar com misturas racémicas e com as atividades biológicas diferenciadas que os enantiómeros geralmente apresentam foi investigado nesta tese. As duas práticas mais comuns na obtenção de enantiómeros puros são a síntese assimétrica e a separação de racematos. Apesar da síntese assimétrica ser considerada a abordagem mais poderosa, esta é limitada pelos elevados custos e complexidade tecnológica. A separação de racematos, por sua vez, representa uma alternativa mais flexível e simples do ponto de vista operacional e de custos. Neste contexto, o uso de SABs formados por LIs quirais foi considerado neste trabalho como uma alternativa na separação de misturas recémicas. Dois conjuntos distintos de LIs quirais, um com quiralidade no catião e o segundo com quiralidade no anião foram sintetizados e aplicados na separação de enantiómeros. Assim, e após caracterização dos diagramas de fase para os diferentes SABs (LI quiral + sal, LI quiral + polímero), foi possível avaliar a sua enantioseletividade na separação dos enantiómeros do ácido mandélico, aplicado neste trabalho como mistura racémica modelo. Numa segunda abordagem, a possibilidade de implementação de solventes eutécticos profundos como solventes quirais foi investigada pelo estudo do impacto da quiralidade no diagrama de equilíbrio sólido-líquido.

Abstract:

Separation of molecular mixtures will often require in chemistry, biology, physics and material science. Existing methods of separation can at best yield a separation factor of 10^4 . They also incur huge expenditure of energy. A new and novel method of separation is proposed in the thesis based on Levitation and Blowtorch effects. This method has been applied for the separation of the four different mixtures, (i) n-pentane-neopentane, (ii) 2,2-dimethyl butane-n-pentane, (iii) n-hexane-neopentane, and (iv) 2,2-dimethyl butane-n-pentane. The results based on Non-Equilibrium Monte Carlo simulations suggest that this method can yield very high separation factors (10^16) with very little consumption of energy. The experimental approach to be employed for the realization of separation is discussed. The changes to the potential energy landscape in the presence of a hot zone are discussed for (i) one-dimensional and three-dimensional systems, (ii) interacting and non-interacting systems, and (iii) hydrocarbons in zeolite system, and compared with Landauer’s suggestion. Extremely small diffusivity of monoatomic species in zeolite NaCaA as a function of diameter of diffusant has been computed with the help of Replica Exchange Transition Interface Sampling (RETIS) technique. Diffusion of a small solute in the body centered cubic lattice is seen to exhibit maxima as a function of the solute diameter. This observation explains the existence of solutes with high diffusivity (for example Co in γ-U and β-Zr, Cu in Pr, or Au in Th). A new potential as a function of Si/Al ratio for modelling zeolite Y and A has been proposed and shown to predict lattice parameter, bulk modulus, infrared spectra, etc in agreement with the experiment.

Abstract:

This work describes the first size dependent magnetic separation in nanoscale. Magnetite (Fe3O4) nanocrystals of high quality and uniform size were synthesized with monodispersity below 10%. Magnetite nanocrystals of 4 nm to 33 nm (average diameter) were produced. Batch synthesis was shown to go up to 20 grams which is more than 10 times of a standard nanocrystal synthesis, without loosing the quality and monodispersity. Reactor design for mass (1 gram per hour) production of magnetite nanocrystals is reported for the first time. The cost of a kg of lab purity magnetite nanocrystals was shown to be $2600. A green synthesis that utilizes rust and edible oils was developed. The cost of a kg was brought down to $22. Size dependency of magnetism was shown in nanoscale for the first time. Reversible aggregation theory was developed to explain the low field magnetic separation and solution behavior of magnetite nanocrystals. Arsenic was removed from drinking water with magnetite nanocrystals 200 times better than commercial adsorbents. Silica coating was successfully applied to enable the known silica related biotechnologies. Magnetite--silica nanoshells were functionalized with amino groups. For the first time, silver was coated on the magnetite--silica nanoshells to produce triple multishells. Anti-microbial activity of multishells is anticipated.

Abstract:

The objective of this work is to develop simple reliable software to observe and quantify diffusion phenomena in microfluidic devices. One of the great advantages of microfluidic technology is that it permits the flow and diffusion of multiple streams in a single channel. The accurate control of a diffusion-based process has applications in bio-analytical chemistry, production of organic compounds and combinatorial chemistry. This method has been discussed in the literature as Laminar Fluid Diffusion Interface technology. It is heavily dependant on the controlled and reproducible introduction of several fluids into one channel and enables the design of separation and detection systems based on laminar fluid diffusion interfaces. A method of analyzing and interpreting the diffusion behavior of multiple microflows using the MATLAB programming language as an image analysis tool is presented here. This paper considers two dimensional brightfield and time series images but the method can be applied to other forms, including fluorescent and three-dimensional images. The approach taken relies on the fact that a digital image stores its colour information in signal channels. The information contained in the channels depends on the colour method being used to define the image. Software-based spectral filtering is performed, yielding three dimensional intensity maps of dyed and clear microflows. These maps can be used to monitor diffusion behavior in a number of different areas simultaneously. Spectral noise reduction techniques are also incorporated without significant reduction in original data quality. The technique is used to determine the aqueous diffusion coefficient of the dye Green S by processing digital images taken at set time intervals of two seconds in a stopped-flow experiment. The approach is applied to microflows in straight, two-dimensional serpentine and three-dimensional serpentine channel configurations.

Abstract:

Abstract Unlike other CCUS technologies, CO2 EOR has been widely implemented at a commercial level and on an industrial scale. In CO2 EOR, CO2 can be injected on its own or alternated with water in CO2 WAG (water-alternating-gas). Both applications have a direct impact on produced fluid compositions influencing GOR, water cut, CO2 concentration and consequently Ca2+, alkalinity and pH. The variation of fluid compositions has an inevitable impact on the scaling potential of produced fluids and on the resulting level of scale formation and its mitigation strategy. The aim of this work is to investigate the scaling potential changes for a wide range of CO2 WAG scenarios in a high salinity carbonate reservoir in the Middle East using input data from reservoir modelling simulations and running multiple sensitivity studies. The main scale formed in this reservoir is calcium carbonate (CaCO3). The equilibrium reservoir water, the produced water chemistry profiles from downhole to stock tank and the scaling risk profiles are modelled using a commercial integrated PVT and aqueous phase software. A rigorous scale prediction procedure previously published by the authors is applied to accurately calculate scale risk trends for variable production scenarios. As CO2 increases in the WAG cycle, reservoir pH drops but the equilibrium with CaCO3 rock causes an increase in alkalinity. This results in more CaCO3 precipitation in the production system where pressure drops and CO2 flashes off solution. Hence, these results show unequivocal detrimental impact of CO2 WAG on the calcium carbonate scaling potential of produced fluids. This leads to a need for operational and/or chemical adjustments to the scale management program when this technology is deployed. Whilst in this field some CaCO3 scale is predicted to form downhole, but this is not a severe problem although it may need to be addressed. The separator is operated at a sufficiently high pressure that calcium carbonate is not expected to form there. Changing operating pressures and CO2 and H2S concentrations can shift some of the problem to the separator, but if this remains at high pressure there will be no scale precipitation here. However, the calcium carbonate scale will predominantly precipitate at stock tank conditions. Implementing green technologies such CCUS is fundamental to achieving net zero goals and this work clearly shows that actions need to be taken to manage the associated CaCO3 scale problems in the produced fluids to make this application successful.
