An aliphatic or cycloaliphatic hydroperoxide or aliphatic dihydroperoxide, an olefin such as alpha-methylstyrene or a substituted alpha-methylstyrene wherein the substituent is on the phenyl ring and a t-cumyl halide corresponding to the hydrohalogenated olefin such as t-cumyl chloride or a substituted t-cumyl chloride are reacted under relatively non-aqueous conditions, in the absence of a free acid and in the presence of a phenol catalyst, to obtain a cumyl (or substituted cumyl) peroxide or diperoxide corresponding to the hydroperoxide or dihydroperoxide. The cumyl peroxides prepared by this reaction are very useful as crosslinking agents for polyethylene and elastomers.
一种脂肪族或环脂族过氧化氢或脂肪族二氢过氧化物、烯烃如α-甲基苯乙烯或取代α-甲基苯乙烯,其中取代基位于苯环上,以及对应于氢卤化烯烃的t-叔丁基卤化物,例如t-叔丁基氯化物或取代t-叔丁基氯化物,在相对非水条件下,在无自由酸存在的情况下,在苯酚催化剂的存在下反应,以获得与过氧化氢或二氢过氧化物相对应的叔丁基过氧化物或二过氧化物。通过这种反应制备的叔丁基过氧化物在聚乙烯和弹性体的交联剂中非常有用。
