1,2-epoxy-cyclohexane, and dicumyl peroxide The method of preparing

The invention relates to a method for preparing 1,2-cyclohexene oxide and dicumyl peroxide, and mainly solves the problems that when the 1,2-cyclohexene oxide is independently produced and an essential raw material of the dicumyl peroxide, namely alpha, alpha-dimethyl benzyl alcohol is independently produced, the production processes pollute environment seriously, the quality of products is low, and production cost is high in the prior art. The method comprises the following steps of: a) performing contact reaction of cyclohexene serving as a raw material, dimethylbenzyl hydroperoxide dissolved in a solvent, and a catalyst in an oxidation-reduction reaction device to obtain a material flow I; b) allowing the material flow I to enter a separating column and rectifying and separating to obtain a material flow II on a column top and a material flow III containing alpha, alpha-dimethyl benzyl and dimethylbenzyl hydroperoxide; c) refining the material flow II to obtain a product 1,2-cyclohexene oxide; and d) allowing the material III to enter a condensation reactor, and performing condensation reaction of alpha, alpha-dimethyl benzyl and dimethylbenzyl hydroperoxide at the presence of a condensation agent to obtain a product dicumyl peroxide. The technical scheme solves the problem well and can be used for the industrial production of 1,2-cyclohexene oxide and dicumyl peroxide.
