Method for producing epoxypropane from cumene hydroperoxide and propylene

The invention relates to a method for producing epoxypropane from cumene hydroperoxide and propylene, which mainly solves the problems of higher reaction temperature rise and higher propylene/cumene hydroperoxide mole ratio required for keeping higher reaction efficiency in the prior art. The method comprises the following steps: raw materials cumene hydroperoxide and propylene liquid phase enter a multisection adiabatic reaction region composed of at least two sections, and the raw materials contact a Ti-silicon dioxide catalyst to perform epoxidation reaction at 15-160 DEG C under the pressure of 1.0-12.0 MPa under the condition that the total mole ratio of the propylene to the cumene hydroperoxide is 2-30, thereby generating the epoxypropane, wherein the raw material cumene hydroperoxide sectionally enters various catalyst bed layers of the multisection adiabatic reaction region, and the epoxypropane-containing epoxidation product is partially circulated to the catalyst bed layer inlets of the 2nd-nth sections of the multisection adiabatic reaction region. The technical scheme well solves the problems, and can be used in industrial production of epoxypropane by cumene hydroperoxide and propylene epoxidation.
