Process method for preparing [1-(4-vinylphenyl)-1, 2, 2-triphenyl] ethylene

The invention discloses a process method for preparing [1-(4-vinylphenyl)-1, 2, 2-triphenyl] ethylene, comprising the following steps of: 1, styrene used as a raw material reacts with a benzoic acid compound under the action of a catalyst to obtain 4-vinylbenzophenone; and 2, 4-vinyl benzophenone as a raw material reacts with benzophenone under the action of a catalyst so as to obtain [1-(4-vinylphenyl)-1, 2, 2-triphenyl] ethylene. The process method is reasonable in route design, cheap in raw material price and friendly to operators. 本发明公开了一种制备[1-(4-乙烯基苯基)-1,2,2-三苯基]乙烯的工艺方法，包括步骤一：以苯乙烯为原料，与苯甲酸类化合物在催化剂作用下反应，得到4-乙烯基二苯甲酮；步骤二：以4-乙烯基二苯甲酮为原料，与二苯甲酮在催化剂作用下反应，得到[1-(4-乙烯基苯基)-1,2,2-三苯基]乙烯。其路线设计合理，原料价格便宜，对操作人员友好。
