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.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.
