本文用羟基取代四苯基卟啉锰通过醚键与聚苯乙烯树脂键联,合成了一类高分子负载化锰卟啉化合物。经ESR、IR、UV-vis散射光谱等测定证实其结构。本文同时考察了它们对烯烃环氧化反应的催化活性,结果表明,负载化金属卟啉在催化烯烃环氧化反应中能集均相和多相催化的优点于一体,不仅催化剂稳定性增强,而且易于分离和重复使用。
In this paper, a series of macromolecule supported manganese porphyrin compounds were synthesized by the hydroxy-substituted tetraphenylporphyrin manganese bonded to the polystyrene resin via ether bond. The structure was confirmed by ESR, IR and UV-vis scattering spectra. In the meantime, the catalytic activities of these catalysts for the epoxidation of olefins were also investigated. The results showed that the supported metalloporphyrins can be used to catalyze the epoxidation of olefins in the homogeneous and heterogeneous catalysis. The stability of the catalyst is not only enhanced, And easy to separate and reuse.
