摘要： 合成了新型的磷钼杂多酸离子液体 [hmim]3PMo12O40, 并将其用于室温离子液体 1-甲基咪唑四氟硼酸盐 ([hmim]BF4) 为溶剂的模拟油品氧化脱硫反应. 结果表明, 在温和的反应条件下, 过氧化氢与硫摩尔比为 4:1 时, 二苯并噻吩脱硫率为 90%, 二苯硫醚、苯甲硫醚和二乙硫醚的脱除率可达 100%. 离子液体催化体系循环使用 4 次后, 脱硫率没有明显下降.

Abstract: Oxidative desulfurization of dibenzothiophene and other sulfides in ionic liquid for model oil was investigated over molybdophosphate-based ionic liquid [hmim]3PMo12O40. Under the mild conditions, high desulfurization was obtained for dibenzothiophene (90%) and dialkyl sulfides (100%). The effects of catalyst, reaction temperature, and amount of H2O2 were investigated. The ionic liquid can be recycled 4 times without a significant decrease in activity.

Key words: molybdophosphate-based ionic liquid, dibenzothiophene, hydrogen peroxide, oxidative desulfurization
