Neohexene was prepared through two steps from commercial tertbutyl bromide to 1neohexyl bromide via addition reaction of ethylene which was catalyzed by anhydrous AlCl3 along with the assistant catalysts and to neohexene via dehydrohalogenation of the intermediate neohexyl bromide in the solvent of 1methyl2pyrrolidone with reactiondistillation system.
9～1MPa、反应时间为2h,产物卤代新己烷的收率达到88%;N-甲基吡咯烷酮为溶剂,采用反应精馏的方法,溴代新己烷脱溴化氢制备新己烯,直接可得到纯度达98%的产品。
