Epoxidation of Methylallyl Chloride with Hydrogen Peroxide Catalyzed by TS-1

Abstract Epoxidation of methylallyl chloride(MAC)with 30%(wt)dilute H_2O_2 solution as oxidant over TS-1 is investigated in this paper.Effects of many factors such as solvent and its dosage,temperature,the mole ratio of the reactants(MAC��H_2O_2),and TS-1 concentration on epoxidation are considered.The results showed that methanol is the proper solvent and the appropriate volume is 80 mL.With the increase of TS-1 concentration and the temperature,the conversion,the yield and H_2O_2 utilization are improved,while the selectivity decreased.If the conversion and H_2O_2 utilization are considered,it is best for epoxidation when the mole ratio of the reactants is 1��1 under conditions of the experiment.
