Oxidation of heterocyclic thiophene
derivatives by ionic liquid with brønsted acidity
Abstract
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 oC, 120 min, 1,5 ml CH3CN.
Key words: ionic liquid with
Brønsted acid centers, molybdate containing catalysts, polyfunctional
catalysts, hydrogen peroxide, oxidative desulfurization.
