Abstract

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.
