OXIDATION OF HETEROCYCLIC THIOPHENE DERIVATIVES BY IONIC LIQUID WITH BRØNSTED ACIDITY
Catalyst based on ionic liquid consisting of pyridinium cation, with Brønsted acid center and anion with molybdenum - molybdate 1-butyl-3-carboxypiridine has been synthesized. This catalytic activity in oxidative desulfurization was investigated. Oxidation reaction of kinetics, temperature of effect, the amount of oxidizing agent and catalyst mass on the conversion of DBT has been studied. A 100% conversion of DBT was achieved in the presence of catalyst under condition of the molar ratio H2O2 : S = 10:1, m(cat) = 0,02 g, 50 оС, 120 min, 1,5 ml СH3CN.
