摘要
本文合成了一类带疏水性长链的对称卟啉及其金属配合物,研究了该类金属卟啉在CH_2Cl_2/H_2O两相体系中催化苯乙烯的环氧化反应性能。通过以上研究,发现催化反应体系中水相pH值对烯烃环氧化反应有很大影响;改变金属卟啉的疏水性对催化反应影响不大;具不同中心金属离子的金属卟啉有不同的催化活性,催化活性顺序为:Mn>Co>Ni>Cu。
A new type of symmetric metalloporphyrins appended with long chain alkyl groups as hydrophobic groups has been synthesized and their catalytic performance in the epoxidation of styrene in CH2C12/H2O two- phase system has been studied. The results of epoxidation of styrene shown that the pH value of the aqueous phase plays an important role in the epoxidation; the influence of hydrophobicity of metalloporphyrins on the catalytic reaction is very small and the order of catalytic-activity of hydrophobic metalloporphyrins is Mn>Co>Ni>Cu.
