摘要: Disclosed herein is a method for preparing epichlorohydrins by reacting allyl chlorides with an alkyl hydroperoxide in the presence of a modified catalyst formed by substituting specific substituents for 1 to 50% of the silanol groups of a catalyst having titanium atoms bound to a silicon dioxide carrier via oxygen atoms and having on the same carrier 1 to 6 silanol groups per square nanometer thereof.
