ABSTRACT:
The present invention is directed to a method for preparing epichlorohydrins by epoxidizing allyl chlorides with an organic hydroperoxide, and the epoxidation reaction is performed in the presence of a catalyst having titanium atoms bound to a silicon dioxide carrier and having silanol groups on the same carrier, whereby epichlorohydrins are obtained in high yield.
