在交联聚苯乙烯微球表面实现苯基卟啉的同步合成与固载

以键合有对羟基苯甲醛(HBA)的交联聚苯乙烯(CPS)微球HBA-CPS、苯甲醛和吡咯为反应物, 采用Adler方法, 实现了苯基卟啉(PP)在CPS表面的同步合成与固载, 制得了固载有苯基卟啉的微球PP-CPS. 研究了卟啉同步合成与固载过程的影响因素, 同时进行了微球PP-CPS与钴盐的配合反应, 制备了固载有钴卟啉(CoP)的功能微球CoP-CPS, 初步考察了其对分子氧氧化乙苯的催化活性. 实验结果表明, 在苯基卟啉同步合成与固载的反应过程中, 催化剂的酸性与溶剂的极性是两个主要的影响因素, 使用强极性溶剂与pKa在2.8~3.4范围的酸, 微球PP-CPS表面的苯基卟啉固载量高. 微球CoP-CPS对分子氧氧化乙苯的反应具有明显的催化活性.

Synchronistic Synthesis and Immobilization of Phenyl Porpherin on Crosslinked Polystyrene Microspheres

Synchronistic synthesis and immobilization of phenyl porpherin on crosslinked polystyrene microspheres(CPS) were realized successfully using benzaldehade,pyrrole and the microspheres HBA-CPS,on which hydroxyl benzaldehyde was bound,as the reactants and with Adler method,and the microspheres PP-CPS,on which phenyl porphyrin(PP) was immobilized,was prepared.In this investigation,the effects of the main factors on the process of synchronistic synthesis and immobilization of phenyl porpherin were studied.The co...
