Three-dimensional mesoporous gallosilicate with Pm3n symmetry and its unusual catalytic performances

Three-dimensional, mesoporous-cage-type, GaSBA-1 materials with different nSi/NGa ratios have been successfully prepared for the first time by using a low hydrochloric acid to silicon (nHCl/n Si) molar ratio in

Investigation of catalytic activity of CrSBA-1 materials obtained by direct method in the dehydrogenation of propane with CO2

A series of the Cr-containing SBA-1 (xCrSBA1) cubic mesoporous catalysts with various Cr/Si molar ratios have been prepared by direct method using cetyltriethylammonium bromide, ammonium dichromate, tetraethyl orthosilicate and hydrochloric acid. The obtained materials have been characterized by different physicochemical techniques including ICP, XRD, UV-vis DRS, H2-TPR and N2-adsorption. XRD and N2-adsorption results have revealed that xCrSBA1 materials possess well organized three-dimensional pore structure. However, incorporation of Cr into the SBA-1 framework leads to small perturbation of the structural order. ICP results have shown that the amount of Cr incorporation in SBA-1 can be controlled by adjustment of the molar ratio of (NH4)2Cr2O7 to Si(C2H5O)4 in the gel. Finally, the catalytic activity of pure SBA-1 and Cr-containing SBA-1 materials were investigated in the dehydrogenation of propane with CO2. In the case of the most active, 0.04CrSBA1 catalyst, the effect of various reaction parameters such as, reaction temperature, reaction time and feed gas composition on the conversion of propane, yield and selectivity to propene as well as on molar ratio of CO/H2 has been evaluated. Moreover, stability of the catalyst during the dehydrogenation/regeneration conditions was studied as well. It has been found that during the fourth consecutive cycle the catalyst undergoes two types of deactivation processes - reversible and irreversible. The former is caused mainly by the coke deposition, which can easily overcome by air treatment of the catalyst at 550 °C. The latter one, insignificant, is due to partial collapse of mesoporous structure of the catalysts.

Effect of Head-Group Size on Micellization and Phase Behavior in Quaternary Ammonium Surfactant Systems

The micellization and phase equilibria in aqueous solutions of cationic quaternary ammonium bromide surfactants of the type alkyltrimethyl-, -ethyl-, -propy-, -butyl-, and -pentylammonium bromide have been investigated as a function of alkyl chain length, electrolyte concentration, and temperature.A large isotropic (micellar) phase is observed in triethyl- and tripropylammonium surfactants, which demixes into two conjugate phases on warming in the case of the alkyltributylammonium bromides.Liquid-liquid phase separation is also observed for tetradecyltripentylammonium bromide.Critical micelle concentrations are found to decrease with increasing hydrophobicity of the surfactant ion, but the free energy of micellization of tetradecyltributylammonium bromide is the same as that of tetradecyltrimethylammonium bromide over a range of temperatures.Some evidence is found for the formation of premicellar aggregates in tributylammonium surfactants at elevated temperatures, consistent with significant polydispersity and changing monomer concentrations observed previously.The results are discussed in terms of the hydrophobic and electrostatic contributions of the free energy of micellization, and some interferences are drawn regarding the nature of the interactions which give rise to phase separation.

Synthesis of ω-hydroxy quaternary ammonium bolaform surfactants

Several members of a novel class of ω-substituted asymmetric bolaform surfactants have been synthesized in order to investigate their surfactant and biological properties. The ω-hydroxy trialkylammonium and pyridinium surfactants have significant antimicrobial and antifungal activity relative to their conventional analogues. For conventional quaternary ammonium alkyl surfactants, increasing the hydrocarbon chain length causes a decrease in the surfactant monomer solubility and a corresponding decrease in the biological activity. No such trend is observed for the ω-hydroxy quaternary ammonium bromide series.

Enantioselective cleavage of esters by histidine-containing tripeptides in micellar solutions of various hexadecyltrialkylammonium bromide surfactants

Cleavage of chiral p-nitrophenyl esters derived from the amino acid phenylalanine by histidine-containing tripeptides has been studied in micellar solutions of four quaternary ammonium surfactants.Enzyme-like enantioselectivities up to kL/kD = 131 (at 0 deg C) are observed.The enantioselectivity can be rationalized by assuming a hydrophobically driven stabilizing hydrogen bond between the L enantiomer of the ester and the tripeptide in the transition state of the reaction.This hydrogen bond is absent in the reaction with the D enantiomer of the ester.The transition state has an amphipolar character and is stabilized by the micellar environment.The hydrophilic-hydrophobic balance of the reactants, which affects the transition state, was optimized by varying the composition of the tripeptide and the length of the N-protecting groups in the tripeptide and the substrate.The activities and enantioselectivities depend on the structure of the quaternary ammonium surfactant headgroup.Increasing the size of this headgroup leads to an increase in rate of hydrolysis of the L ester and hence to an increase in enantioselectivity.This effect is attributed to a change in the degree of ion-pair formation with a carboxylate group that is present in the peptides.Compared to previous studies the results indicate that a chiral surfactant is not required for obtaining high enantioselectivities.
