When the addition is complete after 45 minutes, the whole is allowed to stir for two and one-half hours at 0°-5° C., after which 80 ml. of cold water is added and the whole is stirred for an additional half hour at 0°-5° C. The resulting white precipitate is collected by filtration, washed with 55 ml. of cold methanol in three separate portions, and allowed to dry yield p-t-butylbenzoyl peroxide as a fine white powder; m.p. 149° C.
