摘　　要：以对(间)二异丙苯为原料经过过氧化反应、还原反应、双叔丁基过氧化二异丙苯(BIPB)的合成三步反应合成双叔丁基过氧化二异丙苯。研究了物料配比、温度、时间、压力、搅拌装置等条件对合成交联剂BIPB的影响,确立了产品的质量指标,得到了优惠反应条件:以空气作为氧化剂,过氧化时间60 h,反应压力1.0 MPa,过氧化温度120°C,以亚硫酸钠作为还原剂。在硫酸介质中合成BIPB。总收率≥63.5%(以二异丙苯计)。Bis （tert-butylperoxy） diisopropyl benzene was synthesized from diisopropyl benzene by peroxidation,reduction, synthesis of BIPB. The effects of reaction conditions such as feeding ratio, time, temperature,pressure and agitator etc on the percentage yield of the product were studied. The optimum reaction conditions were as fallows air as oxidant, pressure 1.0 MPa, peroxidation time 60 h, peroxidation temperature 120℃, Na2SO3 as reductant. BIPB was synthesized in the presence of sulfuric acid. The product specifications were established. The yield of product could be more than 63.5%.
