Production of peroxide having polymerizable unsaturated group

Abstract

Abstract PURPOSE:To produce the titled compound in high yield, by dehydrating alpha,alpha'-dihydroxydiisopropylbenzene with an acid catalyst in the presence of water and organic solvent, and reacting the product with a hydroperoxide in the presence of an acid catalyst. CONSTITUTION:The objective compond of formula IV is produced by (1) dehydrating alpha,alpha'-dihydroxydiisopropylbenzene of formula I with an acid catalyst (e.g. benzenesulfonic acid) in the presence of water and an organic solvent (e.g. benzene) in a heterogeneous reaction system, and (2) reacting the produced compound of formula II with a hydroperoxide of formula III (n is 1-2; when n=1, R is 1-5C straight or branched chain alkyl, etc.; when n=2, R is -CH2-CH2-, etc.) in the presence of an acid catalyst. The by-production of various compounds having alpha-hydroxyisopropyl group, isopropenyl group, and alpha-alkylperoxyisopropyl group in combination can be suppressed by carrying out the reaction under the above condition.
