以十六烷基三甲基溴化铵(CTMAB)为模板剂,制备了改性中孔分子筛Zr-FSM-16、Al-FSM-16和Zr-Al-FSM-16,并用XRD、SEM、IR及BET等技术手段对分子筛进行表征.在无溶剂条件下,考察了它们对2-甲基吲哚与环己烯-2-酮的Michael加成反应合成药物中间体3-(2-甲基-1H-吲哚-3-基)环己酮的催化活性.实验结果表明,Al、Zr掺杂进入分子筛骨架中,导致分子筛孔道变大,而骨架结构没有明显改变;Al、zr掺杂改性的FSM-16分子筛催化剂活性有了较大提高,其中Zr-FSM-16分子筛催化剂表现出较好的活性.在催化剂用量7.5％、2-甲基吲哚与环己烯-2-酮的摩尔比1.0∶1.1、反应温度80℃、反应时间120 min的较优条件下,2-甲基吲哚转化率达到75.4％.
