Epoxidation of allyl choride with molecular oxygen and 2-ethyl-anthrahydroquinone catalyzed by TS-1

Epichlorohydrin was prepared by direct epoxidation of allyl chloride with O2 in the presence of 2-ethyl anthrahydroquinone and TS-1 under mild conditions. TS-1 shows high selectivity. Separated by distillation, the working solution is recycled
