PURPOSE:To efficiently carry out epoxidation and obtain the subject compound useful as polyurethanes or an organic synthetic intermediate, etc., by oxidizing an olefin in the presence of a specific crystalline substance. CONSTITUTION:An olefin is oxidized with hydrogen peroxide in the presence of a catalyst of a crystalline substance, containing silicon oxide and titanium oxide and having <10000Angstrom crystallite size to afford an epoxide. For example, propylene oxide, epichlorohydrin or a long-chain olefin epoxide is obtained according to the above-mentioned method. The aforementioned reaction is carried out as follows: The olefin is reacted with an aqueous solution of hydrogen peroxide together with or without a solvent in the presence of the crystalline compound having the above-mentioned crystallite size. |
