摘要: 在没有任何有机溶剂和卤素的条件下,以质量分数30% 的H2O2 为氧化剂,Na2WO4·2H2O 为催 化剂,在酸性离子液体[(CH2) 4SO3HMIm]TSO 中,将柴油中的噻吩硫氧化为砜类物质,并通过离子液体将其萃取, 同时考察了反应温度、反应时间和离子液体用量等因素对氧化脱硫反应的影响,得出最佳反应条件:3mL油样(含 硫质量分数为500μg/g),n(离子液体)/n(Na2WO4·2H2O)=40∶1,0.7mL双氧水,333K ,2h,脱硫率为97. 4%。反应结束后,通过简单的倾倒将油样和催化剂分离,重复使用4次,其催化活性基本不变。

Abstract: Without any organic solvents and halide, the oxidation of thiophenic sulfur into sulfone which would be extracted by the ionic liquid catalyzed by Na2WO4·2H2O with mass fraction of 30% hydrogen peroxide in acidic ionic liquid [(CH2)4SO3HMIm]TSO was investigated. Effects of temperature, reaction time and amount of catalyst on the reaction of oxidative desulfurization were also investigated. The optimal reaction conditions are as follows: 3 mL oil sample (500 μg/g sulfur content), the ratio of 40∶1 for n(IL)/n(Na2WO4·2H2O), 0.7 mL hydrogen peroxide, reaction temperature of 333 K and reaction time of 2 h. And the rate of desulfurization is 97.4% under this condition.When the reaction was completed, diesel oil and catalyst could be separated by simple decantation. The catalyst could be recycled 4 times without obvious change in catalytic activity.
