采用全新的绿色环保工艺制备环己烯:在温度为140℃、空速为0.8h-1的条件下,氯代环己烷在SrCl2/活性炭催化剂的作用下气相脱除氯化氢得到环己烯,氯代环己烷反应转化率为40%,环己烯选择性为98%左右,精馏后的环己烯含量可以达到98.5%,反应产生的氯化氢可以回用于甘油氯化生产二氯丙醇,几乎不产生三废,是真正的绿色环保工艺。 Cyclohexene was prepared by a new green process: Cyclohexene was obtained by gas-phase removal of chlorinated cyclohexane under the action of SrCl2 / activated carbon catalyst at a temperature of 140 ℃ and a space velocity of 0.8 h-1, Chlorocyclohexane conversion of 40%, cyclohexene selectivity of about 98%, cyclohexene after rectification can reach 98.5%, the reaction of hydrogen chloride can be used for the production of dichlorohydrin glycerin Alcohol, almost no waste, is a real green technology.
