新型钨酸盐的合成及催化环氧化环戊烯反应

Synthesis of decatungstate and catalysis in cyclopentene epoxidation

合成了新型喹啉十聚钨酸盐化合物[C3Quin]4W10O32,并对该化合物催化环氧化环戊烯的反应进行研究.考察了催化剂([C3Quin]4W10O32),氧化剂(UHP),反应溶剂([Bmim]BF4)和反应时间等因素对反应收率的影响,优化出最佳反应条件:在反应温度35℃,环戊烯1mmol,催化剂15μmol,氧化剂2.5mmol,离子液体0.4mL,反应时间8h,环氧环戊烷产率达到99%.

A new type of decatungstate [C3 Quin]4 W10 O32 was synthesized and applied lyst in cyclopentene epoxidation. The effects of [Bmim]BF4 and reaction time on the yield dition of ep catalyst（15 oxidation was suggested： at 35 different amounts of [C3 Quin-]4Wl0 O32 as cata- , UHP, are systematically studied. The optimal reaction con- ℃, cyclopentene （1 retool）, [Bmim]BF4 （0.4 rnL）, μmol） and UHP（2.5 mmol） were used for 8 h, and the epoxide yield reached 99%.
