中文摘要:
      研究了磷钨杂多酸盐对氯丙烯与H2O2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.
