摘要： 采用酸性离子液体和磷钨酸合成了7种新型的咪唑类磷钨杂多酸盐离子液体,分别用XRD、TG 及 SEM 进行了表征。XRD表征表明7种磷钨杂多酸盐均保持有keggin结构;TG 表征表明其热稳定性良好;SEM 表征说明其表面结构良好。将其用于模拟油品的氧化脱硫反应,考察了反应时间、反应温度、H2O2 的用量等因素对此反应的影响。结果表明,在反应温度为45℃,反应时间为1h,n(S)/n(催化剂)=300:1,n(H2O2)/n(S)=4:1的条件下,脱硫率可达到99.72%。反应结束后,催化剂容易分离,干燥后可重复使用7次,脱硫率没有明显下降。

Abstract: Seven different dodecatungstophosphates were prepared by using acidic ionic liquids and 12tungstophosphoric acid, and were characterized by XRD, TG and SEM. The result of XRD show that the molecular compound kept keggin structure. TG illustrate that they possessed good thermal stability. SEM result show that the surface structure of the catalyst is good. And their catalytic application in the oxidative desulfurization from fuel had also been investigated. The effect of reaction time, reaction temperature, the dosage of H2O2 were also studied. The sulfur removal (99.72%) was obtained under the following condition: reaction temperature 45 ℃，reaction time 1 h, n(S)/n（catalyst）=300∶1, n(H2O2)/n(S)=4∶1. After reaction, the catalyst is easy to separate, and can be reused 7 times after drying without obvious catalytic loss.
