A method for the synthesis of 1,3-di(chloropropyl)-5-tert-butyl benzene includes the steps of conducting Friedl-Crafts alkylation of 1,3-diisopropyl benzene by tert-butyl chloride in the presence of an alkylation catalyst to obtain 1-tert-butyl-3,5-diisopropylbenzene; peroxidizing the 1-tert-butyl-3,5-diisopropyl benzene by gaseous oxygen in the presence of a peroxidation catalyst in a basic solution to obtain 1,3-di(peroxypropyl)-5-tert-butylbenzene; reducing the 1,3-di(peroxypropyl)-5-tert-butylbenzene with a reducing agent to 1,3-di(hydroxyl propyl)-5-tert-butylbenzene; and chlorinating the 1,3-di(hydroxypropyl)-5-tert-butylbenzene to obtain 1,3-di(chloropropyl)-5-tert-butyl benzene.
一种合成1,3-二(氯丙基)-5-叔丁基苯的方法,包括以下步骤:在烷基化催化剂的存在下,通过Friedl-Crafts烷基化反应,用叔丁基氯烷基化1,3-二异丙基苯,得到1-叔丁基-3,5-二异丙基苯;在碱性溶液中,通过过氧化催化剂的存在和氧气气体的过氧化作用,将1-叔丁基-3,5-二异丙基苯过氧化,得到1,3-二(过氧丙基)-5-叔丁基苯;用还原剂将1,3-二(过氧丙基)-5-叔丁基苯还原成1,3-二(羟丙基)-5-叔丁基苯;然后将1,3-二(羟丙基)-5-叔丁基苯氯化,得到1,3-二(氯丙基)-5-叔丁基苯。
