Four kinds of Brφnsted acidic ionic liquids with nitrogen chem. groups and different anions were synthesized. The kinetics of esterification of Me oleate was studied using Brφnsted acidic ionic liquids as the catalysts. Through experiments of kinetics and by Matlab programs and regression of the exptl. data, the reaction dynamics parameters were determined and the reaction dynamic model was set up. The catalytic activities of ionic liquids were investigated. The results that showed under the coaction of anions and cations, the kinetic equation of esterification was as follows: r=k(cA0-x)1.72(cB0-x)2.01-k-1x1.85, and the sequence of reaction rate constants k of nine kinds of ionic liquids in catalyst system was as follows: [MPy]HSO4 > [Py]HSO4 > [Et3NH]HSO4 > [MPy]H2PO4 > [Py]H2PO4 > [Et3NH]H2PO4 > [HMIm]HSO4 > [HMIm]H2PO4 > [MPy]NO3. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Product Details of 478935-29-4).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Product Details of 478935-29-4
