摘　　要：研究了２，９，１６，２３四羧基铁（Ⅲ）、钴（Ⅱ）酞菁及固载在硅胶上的２，９，１６，２３四甲酰胺基铁（Ⅲ）、钴（Ⅱ）酞菁，在水溶液中催化硫醇氧化的反应，比较了几种催化剂的性能，考察了反应条件对硫醇氧化反应的影响，提出了反应机理。结果表明，当硫醇浓度较高时，固载后的酞菁铁，其催化性能优于或接近未固载的酞菁铁；而当硫醇浓度较低时，固载后的金属酞菁显示出更接近实际的优越性。而两种金属酞菁固载后仍具有良好的催化性能，具有一定的应用前景。The catalyzed oxidation of 2mercaptoethanol by phthalocyanineiron(Ⅲ), phthalocyaninecobalt(Ⅱ) and both of them being fixed on silicagel in aqueous medium were studied Their catalytic characters were compared with each other and the effects of the reaction condition were discussed The results showed that both of the two catalysts which were fixed on the silicagel have good catalytic activities
