It is indicated that both the coverage of the bulkier molecules in active centre of catalyst and the loss of the active component in catalyst by the reaction of chloric species with water in feed contribute to the deactivation of catalyst.

• 通过对失活催化剂的分析发现,在苯与烯烃烷基化反应中,固载化AlCl_3催化剂的失活主要是因为反应过程中生成的大分子物质覆盖在催化剂的活性中心上,以及担载在催化剂上的含氯活性物种的流失和原料中的水使催化剂活性组分分解所致。
