2,2-dinethyl butane

Neohexene was prepared through two steps from commercial tertbutyl bromide to 1neohexyl bromide via addition reaction of ethylene which was catalyzed by anhydrous AlCl3 along with the assistant catalysts and to neohexene via dehydrohalogenation of the intermediate neohexyl bromide in the solvent of 1methyl2pyrrolidone with reactiondistillation 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。
