Full textLa reacción de hidrogenólisis para obtener 1,3-propandiol (1,3-PD) a partir de glicerol requiere el uso de costosos metales nobles y elevadas condiciones de reacción. Aún así, no se debe olvidar el bajo rendimiento obtenido en 1,3-PD bajo estas condiciones. Glycidol, el cual puede ser obtenido por reacción directa de glicerol, fue propuesto como una alternativa para la síntesis de 1,3-PD utilizando Ni y Cu como catalizadores. Por lo tanto, el objetivo principal de esta tesis fue la síntesis de saponitas mesoporosas ácidas mediante moldes (sales de amonio cuaternarias o polímeros) y microondas, para finalmente evaluar su actividad en la hidrogenólisis de glicidol para obtener 1,3-PD y 1,2-PD. Saponitas mesoporosas con la mayor área superficial (600 m2/g) y la mayor acidez superficial (0.89 mEq CHA/ g) fueron obtenidas llevando a cabo la síntesis en medio básico (pH 13), usando surfactantes y microondas. Esta y otras saponitas sintetizadas fueron utilizadas como soportes en la preparación de catalizadores de Ni, los cuales fueron testados en la hidrogenólisis de glycidol a diferentes tiempos y temperaturas de reacción. Respecto los catalizadores de Ni soportados, el mejor rendimiento hacia 1,3-PD fue obtenido con catalizadores soportados en saponitas ácidas, con un 40 % en peso de Ni y a 453 K durante 1h. El efecto de varios modificadores (W, Mo, V y Re) fue testado en la reacción catalítica, donde el mejor valor de rendimiento hacia 1,3-PD (46%) con un ratio 1,3-PD/1,2-PD de 1,24 fue obtenido utilizando catalizadores de Ni modificados con Re a 393 K después de 4 h. La presencia de Cu en el catalizador de Ni (catalizadores bimetálicos de Ni-Cu) también tubo beneficios en la formación selectiva de 1,3-PD.
The direct hydrogenolysis of glycerol to 1,3-propanediol (1,3-PD) requires expensive noble metal catalysts, harsh reaction conditions and even then, the yield to 1,3-PD is moderate to low. Glycidol molecule which could be obtained from glycerol was proposed as an alternative substrate for the synthesis of 1,3-PD using cheap transition metal Ni and Cu catalysts. Hence, the main objective of the thesis was to prepare mesoporous acid saponite using template and microwaves and evaluate its activity in the hydrogenolysis of glycidol to 1,3-PD and 1,2-PD. The highest surface area (600 m2/g) mesoporous saponite with high surface acidity (0.89 mEq. CHA/ g) was obtained when the synthesis was carried at pH 13, using surfactant and in microwaves. This and other saponites were used in the preparation of supported Ni catalysts and their activity was tested at different reaction temperature and time. Among the supported Ni catalysts, the best 1,3-PD yield was obtained using Ni catalyst supported at 40 wt % on the mesoporous saponite and when the reaction carried out at 453 K for 1h . The effect of various modifiers (W, Mo, V and Re) on this catalyst was tested and the best result was obtained in case of Re modified Ni catalysts which afforded 1,3-PD at 46% yield with 1,3-PD/1,2-PD ratio of 1,24 at 393 K and after 4 h. The presence of small amount of Cu in Ni-Cu bimetallic catalysts was also found beneficial for the selective formation of 1,3-PD.

Full textPoly(styrene-co-divinylbenzene-co-glycidyl methacrylate) porous microspheres were successfully obtained. All microspheres can be classified as mesoporous materials according to IUPAC. The glycidyl methacrylate containing microspheres obtained using a 30% toluene and 70% heptane mixture as porogenic agent present very rough surfaces with irregular channel distributions. The microspheres specific area and pore volume strongly decrease with increasing glycidyl methacrylate content in the terpolymers. On the other side terpolymers with the same composition synthesized using only toluene as porogenic agent present surfaces with small irregularities (probably pores). Also with this porogenic agent the specific area decreases with increasing glycidyl methacrylate content, but this decrease was much less pronounced. The strong specific area decrease and mechanical fragility increase with increasing glycidyl methacrylate content observed when the 30% toluene and 70% heptane mixture was used as porogenic agent, as well as the hollow microspheres obtained when only heptane was used as porogenic agent indicate that heptane is a bad solvent for the copolymers containing glycidyl methacrylate. Some terpolymers have been preliminarily tested as stationary phase for pesticides recovery tests from aqueous solutions. The tests showed that both the terpolymer composition and the specific area influence the results obtained.

Resumo: O biopolímero quitosana foi quimicamente modificado com a finalidade de inserir diferentes grupos funcionais nas cadeias pendentes, as quais contêm os centros básicos enxofre, nitrogênio e oxigênio, visando o desenvolvimento de novos materiais para a remoção de metais de solução aquosa. Em um procedimento típico, a quitosana reagiu com metacrilato de glicidila através da abertura do anel epóxido de três membros, dispondo da dupla ligação livre. Assim, esse precursor reagiu com aminas: etilenodiamina, dietilenotriamina, trietilenotetramina, 1,4-(3- aminopropil)piperazina, acetilhidrazina e com tióis: 1,2-etanoditiol e 2-aminoetanotiol. A quitosana foi também modificada com o tiocarbamato e diotiocarbamato por meio da reação de adição de Michael, em uma reação de etapa única de três componentes, empregando-se acriloilmorfolina, acrilonitrila e acrilamida como receptores. Os novos derivados modificados obtidos foram caracterizados por meio de análise elementar, espectroscopia na região do infravermelho, ressonância magnética nuclear no estado sólido para o núcleo de carbono, termogravimetria e microscopia eletrônica de varredura. Os novos materiais sintetizados foram empregados para a sorção dos cátions divalentes cobre, cádmio, chumbo e níquel, a partir de soluções aquosas, de modo a explorar as basicidades de enxofre, nitrogênio e oxigênio ligados às cadeias poliméricas. As capacidades sortivas máximas para tais cátions foram obtidas por meio de isotermas de sorção de Langmuir. A quitosana apresenta a seguinte ordem de sorção dos cátions metálicos: Cu > Cd > Ni > Pb, enquanto que para as quitosanas modificadas com amina apresentaram maiores capacidades, atingindo até o valor 2,97 mmol g para o cobre, refletindo a melhora nessa capacidade devido à incorporação de centros básicos, o que difere do valor da quitosana de 1,40 mmol g, para o mesmo cátion. Já as quitosanas modificadas com tióis apresentaram maiores capacidades para o chumbo. Quando a quitosana foi modificada com tiocarbamato os valores de sorção foram 2,54 e 1,65 mmol g para chumbo e cádmio, respectivamente, refletindo o efeito interativo dos ácidos com a propriedade mole do enxofre. Os dados experimentais foram ajustados aos modelos de isoterma de sorção de Langmuir, Freundlich e Temkin, usando os métodos de regressão linear e não linear. Quatro tipos de equações lineares de Langmuir foram utilizados para a melhor comparação desses ajustes. Há uma pequena variação entre as constantes de isoterma calculadas por meio dos métodos linear e não linear para os modelos de isotermas. No entanto, os valores das funções de erro para não linear são menores do que os determinados pelo método linear. As funções de erro para os sistemas lineares, os valores previstos das constantes de Langmuir e coeficiente de determinação são diferentes para cada tipo de equação de Langmuir linearizada. O valor do coeficiente de determinação obtido a partir de Langmuir do tipo 1 é maior do que os das outras três equações linearizadas e do que os dos modelos de Freundlich e Temkin, sugerindo que esse modelo é o que melhor se ajusta aos dados experimentais. Assim, essa forma linear foi a mais adequada para descrever os dados experimentais, em comparação com os outros dois modelos propostos
Abstract: Biopolymer chitosan was chemically modified in order to insert different functional groups on the pendant chains, which contain nitrogen, sulfur and oxygen basic centers to develop new materials for metal removal from aqueous solution. In a typical procedure chitosan reacted with glycidylmethacrylate through opening the three member epoxide ring, disposing double bond free. Thus, this precursor reacted with amines: ethylenediamine, diethylenetriamine, triethylenetetramine, 1,4-(3-aminopropyl)piperazine, acetylhydrazine and thiols: 1,2- ethanedithiol and 2-aminoethanethiol. Chitosan was also modified with thiocarbamate and dithiocarbamate moieties through Michael¿s reaction based on a single step three component using acryloilmorpholine, acrylonitrile and acrylamide as acceptors. The new derivatives obtained were characterized by elemental analysis, infrared spectroscopy, nuclear magnetic resonance in the solid-state for the carbon nucleus, thermogravimetry and scanning electron microscopy. The chemically modified materials were employed to divalent cation sorptions such as copper, lead, cadmium and nickel from dilute aqueous solutions, in order to explore the Lewis basic properties of sulfur, nitrogen and oxygen centers attached to polymeric chains of the biopolymers. The maximum sorption capacities for cations were obtained through Langmuir sorption isotherms. Chitosan presents the following sorption order for metallic cations Cu > Cd > Ni > Pb, while the chemically modified chitosan containing amine showed higher capacity, reaching 2.97 mmol g for copper, reflecting the improvement in sorption capacity, since the amount of copper on pristine chitosan gave 1.40 mmol g. Thiols chitosan derivatives gave highest sorption capacity for lead. When chitosan was modified with thiocarbamate the sorption values were 2.54 and 1.65 mmol g for lead and cadmium, respectively, reflecting the interactive effect of these acids with the soft sulfur property. The experimental data were adjusted to the Langmuir, the Freundlich and the Temkin sorption isotherm models using both linear and non linear regression methods. Four types of Langmuir linear equations were used for better comparison of linear and non linear regression methods. There is a small variation between isotherm constants calculated by linear and nonlinear methods for isothermal models. However, the values of the error functions for non linear are much lower than that determined by the linear method. The error functions for linear systems, the predicted values of the Langmuir constants and coefficient of determination are different for each type of linearized Langmuir equation. The value of the coefficient of determination obtained from Langmuir type 1 is higher than that of the other three linearized equations, the Freundlich and the Temkin models, suggesting that Langmuir type 1 is the bestfitting isotherm compared to the other linear forms. Thus, this linear form is more suitable to describe the experimental data, than the other two models

Full textIn this dissertation, polymeric microspheres with magnetic properties based on glycidyl methacrylate and divinylbenzene were synthesized by suspension polymerization technique. In order to obtain magnetic properties, magnetite particles modified by oleic acid were synthesized in laboratory. The effects of stirring rate, concentration of crosslink, the concentration of magnetite added and the concentration of stabilizer on the particles properties were studied. The magnetic microspheres were characterized according their morphology, thermal stability, incorporation of magnetite and their magnetic properties. The incorporate of iron particles content was mainly affected by stirring rate during the synthesis, by the content of magnetic material added, by the dispersion phase of magnetic material and by the monomers content in the copolymer. The thermal stability of copolymers was mainly affected by the content of magnetic material incorporated and by the monomers content, taking in account the resins with the same content of magnetic material added. The saturation magnetization for the microspheres was effected by the content of magnetic material incorporated. The modification with oleic acid was considered important to the incorporation of the magnetic material in the copolymer matrix.Magnetic polymeric particles with superparamagnetic behavior have been obtained with spherical morphology and saturation magnetization of 7.11 (emu/g). It was used monomers molar ratio of 50/50 %, 1% PVA, 20 % magnetite particles modified by oleic acid dispersion on organic phase and stirring rate of 500 rpm during the synthesis
