Production method of epoxy butane

The invention relates to a production method of epoxy butane and mainly solves the problems of large quantity of waste water and waste residue, serious pollution and strong equipment corrosion in the prior art. In the method, a contact reaction between raw materials with a titanium-containing porous silicon dioxide catalyst to produce the epoxy butane with butylene and an organic peroxide as raw materials at the reaction temperature of 25-200 DEG C under the reaction absolute pressure of 0.1-8.0 MPa, wherein the molar ratio of the butylene to the organic peroxide is 1-15, the concentration of the organic peroxide is 0.5-90 wt% and the weight space velocity of the organic peroxide is 0.01-20/h. The technical scheme solves the technical problems well. The production method can be used in industrial production of the epoxy butane.
