ABSTRACT:
A process for the preparation of dicumyl peroxide by reaction of dimethylbenzyl hydroperoxide (cumene hydroperoxide) with methyl cumyl ether is described. The reaction is carried out in the presence of a catalytic quantity of Lewis or Bronsted acids, the methanol which forms as a by-product being removed as the reaction proceeds. Furthermore, the reaction is carried out in a reaction medium consisting of the methyl cumyl ether itself, which is employed in quantities greater than the stoichiometric quantity required for the reaction with the cumene hydroperoxide.
