中文摘要：

以Ti-MWW分子筛为催化剂,以H2O2为氧化剂,系统研究了氯丙烯环氧化反应的动力学行为.结果表明,该反应速率与Ti-MWW分子筛的用量成正比,是1级反应.当H2O2浓度小于0.67mol/L时,环氧化反应为1级反应;大于2mol/L时,为0级反应.随着氯丙烯浓度的增加,环氧化反应级数从1级向0级转变;且只有当其浓度很高时,反应级数才会明显降低.随着分子筛中Ti含量的增加,氯丙烯环氧化反应速率呈S形变化.

英文摘要：

The reaction mechanism for epoxidation of allyl chloride（ALC） with H2O2 catalyzed by Ti-MWW was studied in detail. The results showed that the epoxidation of ALC is first order reaction with respect to the catalyst amount and is the reactions between zero and first order with respect to the substrate concentration and the oxidant concentration. For H2O2,the epoxidation is first order reaction when its concentration is lower than 0.67 mol/L and zero order when its concentration is higher than 2 mol/L. For ALC,only when its concentration is very high,the obvious decrease of the reaction order from 1 to 0 was observed. And the epoxidation reaction rate is an S-type curve when the Ti content in Ti-MWW increases.
