过氧化二碳酸双(2-乙基)己酯的合成研究

Synsthesis 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-ethylhexy1 peroxydicarbonate(EHP)was synthesized by2-ethylhexy1 chloroformate.The influnce of the feeding method,re- action temperature,reaction time,the radio of reactants and other conditions on the product were studied.Thus,the 2-ehylhexy1 chloroformate and sodium peroxide in mole ratio 1:0.58～0.62reacted at 15℃～20℃for 3～4h and then dissolved in isododecane to give the high efficiency nontoxic EHP solution.
