先通过季铵化反应将吡啶甲醛(PyAL)基团键合于交联聚苯乙烯微球(CPS)表面,制得改性微球PyAL-CPS,再通过Adler反应,成功地实现了吡啶基卟啉(PyP)在CPS微球表面的同步合成与同载,制得功能微球PyP-CPS,它再与碘甲烷发生季铵化反应制成N-甲基吡啶基卟啉(MPyP)季铵盐,从而制得固载有阳离子卟啉的微球MPyP-CPS;最后通过与钴盐的配合反应,制备了固载有阳离子钴卟啉的固体催化剂CoMPyP-CPS.考察了影响吡啶基卟啉在CPS微球表面同步合成与固载的因素,固载化阳离子钴卟啉催化剂CoMPyP-CPS催化分子氧氧化乙苯的反应性能,也考察了CoMPyP-CPS(C)与磷钨杂多阴离子(PW)的复合催化剂CPW的催化性能.结果表明,以改性微球PyAL-CPS与溶液中的吡咯及4-吡啶甲醛为共反应物,通过固-液Adler反应,可以顺利地实现吡啶基卟啉在微球CPS表面的同步合成与固载,所制备的固体催化剂CoMPyP-CPS具有较好的催化分子氧氧化乙苯反应活性,而CPW催化剂的催化活性更高.
