PROBLEM TO BE SOLVED: To produce a di-t-peroxide useful as a polymer vulcanizing agent, etc., using a catalyst effective for improving the yield and suppressing the formation of by-product by carrying out the condensation reaction of a t- hydroperoxide with a t-alcohol in the presence of a specific acid catalyst. SOLUTION: The objective compound (preferably dicumyl peroxide) is produced by the condensation reaction of (A) a t-hydroperoxide (preferably cumene hydroperoxide) with (B) a t-alcohol (preferably cumyl alcohol) in the presence of (C) an acid catalyst composed on a compound having a mono-sulfonated aromatic group and selected from the compounds of formula I and formula II (R is a 2-9C alkyl; R' and R" are each a 1-9C alkyl) (e.g. p-toluenesulfonic acid) preferably at 25-60 deg.C for about 30-90 min. Preferably, the molar ratio of the component A to B is 0.9-1.2 and the amount of the component C is 10-40 wt.% based on the organic mixture used as the reactant.
