The formed long and linear chain alkyl benzene changes into benzene methyl and alkene through - scission and monomolecular homolysis , and then benzene methyl shifts to the position of - carbon in the long chain alkyl benzene through h - transfers 已形成的长直链烷基苯通过分裂、单分子均裂形成苯甲基、烯烃，苯甲基通过氢转移到长链烷基苯的碳上，烯烃再与碳结合形成带支链的烷基苯。
