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.

布朗斯台德酸性离子液体对缩合噻吩衍生物的氧化

摘要-获得了一种基于离子液体的催化剂，该离子液体由具有布朗斯台德酸度的吡啶鎓阳离子和钼阴离子（1-丁基-3-羧基吡啶鎓钼酸盐）组成。研究了其在氧化含硫化合物中的催化活性。还考虑了氧化的持续时间，温度以及氧化剂和催化剂的量对二苯并噻吩（DBT）转化的影响。在以下条件下，在催化剂的存在下，DBT的转化率为100％：H ₂ O ₂：S = 10：1的摩尔比，催化剂质量0.02 g，反应温度50℃，持续时间120分钟。
