Four kinds of Bronsted-acidic ionic liquids with nitrogen-laden functional groups and different anions were synthesized and characterized with NMR, IR spectrum and thermogravimetric anal. In this paper, on this basis, the trans-esterification of triolein and methanol was studied and the catalytic activities of ionic liquids in trans-esterification were investigated. The results showed that their catalytic activities were related with the structures of nitrogen-laden functional groups, anionic acid strength and acid volume Pyridine and Me pyridine ionic liquids, whose anions were HSO4– and H2PO4–, were used jointly to accelerate the reaction and get a higher yield of methyl-ester under the coaction of anions and cations. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Application In Synthesis 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. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. 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).Application In Synthesis of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate
