Full textNuclear Magnetic Reaction (NMR) spectroscopy is a widely employed technique in the detection and quantification of chemical compounds, with a wide range of applications. In this manuscript, the focus is put on two of them: the detection of pollutants in drinking water and the monitoring of chemical reactions. While laboratory NMR equipment presents highly reliable analysis results, portable miniaturized NMR is an evolving research field with multiple technological and application-related challenges. Such emerging devices present however a clear advantage when compared to the classic, stablished ones: it can be used in the field, therefore saving time and limiting staff and consumables costs. In order to design NMR spectrometers to attain the desired portability and miniaturization, one has to compromise, however being able to understand what is at stake, so that the final product still meets the demands. For that, we propose a complete NMR simulation toolchain capable of generating diverse outcomes corresponding to a real NMR spectrometer. Furthermore, we develop a proof of concept for an electronic control and acquisition unit based on commercial-off-the-shelf components and validate it on a portable NMR spectrometer prototype. Finally, we use this prototype to assess the potential of portable miniaturized NMR for the targeted applications cited above. This study allowed us to identify the limits of our current prototypical device and to provide directions for its further improvement

Full textThis endeavour represents a pioneering effort to design and develop a cost-effective low-field Dip-NMR or Immersible NMR system dedicated to monitoring reaction mixtures at the closest possible source of information. While we have successfully designed and optimized the first version of prototype capable of acquiring single scanned NMR spectra of pure samples, further focused study and research are highly warranted to develop and integrate prototype into an immersible probe unit capable of multi-channel acquisition to realize the proposed Dip-NMR system. The NMR spectra obtained from Dip-NMR system were notably broad and necessitated dedicated chemometric methods for quantification and kinetic data extraction. Known reactions were monitored on a high-field high-resolution NMR spectrometer, with the kinetic data from this instrument serving as benchmark data for comparison and evaluation against the data obtained from Dip-NMR system. Various chemometric methods were explored and tested on the mimicked spectra for quantification and kinetic data extraction, with the results subsequently compared with the benchmark data. In parallel with the project’s goal, hydrosilylation reactions involving organic substrates such as nitriles, cyclic amides, and esters were catalyzed using an Ir(III) catalyst and monitored on a high-field high-resolution NMR spectrometer. These investigations have successfully yielded valuable insights into the reactions, contributing to a deeper understanding of the processes involved and laid important reference kinetic data for future testing of an advanced Dip-NMR probe prototype

Full textMaintaining the quality of lubricants is essential because of their key role in machine duration and performance. Oxidation is one of the main causes of oil degradation. To prevent and reduce the consequences of this phenomena in the best possible way, mechanisms must be determined and well understood. An experimental system was built to reproduce, at the lab-scale and in an accelerated mode, the oxidation process of lubricating base oils under temperature close to those existing under working conditions. Mid-infrared spectroscopy has been chosen for on-line monitoring of the chemical changes happening along the process. To understand the oxidation evolution, the spectroscopic data recorded have been analysed with factorization techniques such as Principal Component Analysis (PCA), which has shown the action of iron as catalyst. The use of Multivariate Curve Resolution – Alternating Least Squares (MCR-ALS) method allowed to extract chemical information about the evolution of a substituted diphenylamine antioxidant during the induction period

Full textThe aim of this work was to determine precisely the role played by each of the three pore systems of the MCM-22 zeolite during xylenes transformation at 350ʿC. In the large supercages, the reactant can isomerise but also disproportionate, giving toluene and trimethylbenzenes. The latter, trapped inside the cages, undergo several secondary transformations, leading to the complete deactivation of this pore system after 24 hours of reaction. The role played by the external cups has been determined after poisoning with 2,4-dimethylquinoline. The relative significance of this pore system depend largely on the nature of the reactant but also on the physicochemical properties of the catalyst, and can be responsible for more than 30 % of the initial activity of MCM-22 zeolite. Finally, in the sinusoidal channels, only isomerization between m-xylene and p-xylene can occur, due to the small diameter of these channels
