摘要： 以过氧化氢为氧源,磷钨杂多酸季铵盐为催化剂,研究了α,β-不饱和酮的环氧化反应,考察了溶剂、温度、催化剂用量、反应时间以及底物浓度等因素对环氧化反应的影响. 结果表明,在适宜反应条件下,过氧化氢/磷钨杂多酸季铵盐催化体系可以催化α,β-不饱和酮环氧化,得到相应的环氧化合物,并能取得较好的结果. 其中,4-甲基-3-戊烯-2-酮的环氧化合物的产率达到了87%.

关键词: α, β-不饱和酮, 环氧化, 磷钨杂多酸季铵盐

Abstract: In the presence of H2O2, the epoxidation of α, β-unsaturated ketones cata lyzed by quaternary ammonium heteropolyphosphato-tungstate was studied. The facto rs such as different solvents, reaction temperature, catalyst amount, reaction time, and substrate concentration were investigated. Epoxidation of α , β-unsaturated ketones can be easily performed in this catalytic system. Under the optimized reaction conditions an epoxy-4-meth yl-3-penten-2-one yield of 87% was obtained.

Key words: α, β-unsaturated ketone, epoxidation, quaternary ammonium heteropolyphosphatotungstate
