摘要：
Abstract—A catalyst based on ionic liquid consisting of a pyridinium cation having Brønsted acidity and a molybdenum anion (1-butyl-3-carboxypyridinium molybdate) is obtained. Its catalytic activity in the oxidation of sulfur-containing compounds is studied. The influence of the oxidation’s duration, temperature, and the quantity of the oxidation agent and catalyst on the conversion of dibenzothiophene (DBT) is also considered. The conversion of DBT is 100% in the presence of the catalyst under the following conditions: molar ratio H2O2 : S = 10 : 1, catalyst mass 0.02 g, reaction temperature 50°C, and duration 120 min.
