中文摘要：
研究了磷钨杂多酸盐对氯丙烯与H2O3水溶液两相条件下环氧化反应的催化活性．反应结果表明，环氧氯丙烷的产率受溶剂二氯乙烷量影响；二氯乙烷作溶剂时，这一反应体系具有很好的催化性能，环氧氯丙烷产率可达88．3％；甲苯不是氯丙烯环氧化的优良溶剂．
英文摘要：
The catalytic performance of a heteropolyphosphatotungstate for epoxidation of allyl chloride with aqueous hydrogen peroxide under biphasic conditions was investigated. Experimental results show, the yield of epichlorohydrin is influenced by the amount of solvent 1,2-dichloroethane; while 1,2-dichloroethane serves as solvent, this reaction system possesses rather good catalytic properties, the highest epichlorohydrin yield reaches 88 3% ; toluene is not a good solvent for epoxidation of allyl chloride.
