Five SO3H and CF3SO3H-functionalized ionic liquids (ILs) with different acidity were synthesized. The catalytic performances of various ILs were evaluated for producing biodiesel in the esterification reaction and the yield of biodiesel increased with the increase of ILs’ acid strength. [Bsmim]CF3SO3 was found to be a highly-efficient catalyst for increasing the biodiesel yield due to its greatly enhanced Bronsted acidity, and it was also an environmental friendly solvent for its good recyclability and hydrophilicity. The exptl. design and study were carried out by using the response surface methodol. (RSM) for optimizing the production process. The optimum biodiesel yield of nearly 99% was achieved at the conditions that the catalyst amount of 11%, the molar ratio of methanol to oleic acid of 9:1, the reaction time of 3 h and the reaction temperature of 62 °C were used. In addition, the catalyst showed an excellent reusability. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Quality Control of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Quality Control of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate
