过氧化二碳酸双(2-乙基)己酯的合成研究

Research on Synthesis of Di-2-ethylhexyl Peroxydicarbonate

以氯甲酸(2-乙基)己酯为原料制备过氧化二碳酸双(2-乙基)己酯(EHP),研究了加料方式、反应温度、反应时间、投料比等因素对产品的影响。结果表明:氯甲酸(2-乙基)己酯与过氧化钠的摩尔比为1:0.58～0.62,反应温度为15℃～20℃,反应时间为3～4小时,以异十二烷为溶剂,可以得到高效、无毒的EHP溶液。

Di-2-ethylhexyl peroxydicarbonate (EHP) was synthesized by 2-ethylhexyl chloroformate. The influences of the feeding method, reaction temperature, reaction time, the radio of reactants and other conditions on the product were studied. Thus, the 2-ethylhexyl chloroformate and sodium peroxide in mole ratio 1:0.58 to 0.62 react at 15℃ to 20℃ for 3 hours to 4 hours and then dissolved in isododecane to give the high efficiency nontoxic EHP solution.
