    Abstract: 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.
