将四(4-羧基苯基)锰卟啉[Mn TCPP]固载到硫化锌[ZnS]上制备了固载锰卟啉催化剂[Mn TCPP/ZnS],用UV-Vis、FT-IR和TG技术对其进行了表征,并用此固载催化剂催化氧气氧化环己烷。结果表明:在最适宜反应温度和压力(160℃和0.8 MPa)条件下,硫化锌固载四(4-羧基苯基)锰卟啉可以有效重复使用4次,其环己烷转化率42.6%,酮醇产率18.6%,催化剂转化数6.0×105,比未固载的Mn TCPP具有更好的催化活性和重复使用性能。

Manganese tetrakis (4-carboxylpheny1) porphyrin was supported to zinc sulfide to obtain ZnS supported manganese tetrakis (4-carboxylphenyl ) porphyrin and characterized by UV-Vis, FT-IR and TG spectroscopic techniques .The catalysis of the ZnS-supported tetrakis (4-carboxylphenyl ) porphyrin for aerobic oxidation of cyclohexane was investigated .The results show that the supported catalyst could be efficiently reused 4 times for the oxidation of cyclohexane with an average conver-sion rate of 42.6%for cyclohexane and 18.6%yield for ketone and alcohol , and a catalyst turnover number of 6.0 ×10 5 , under the optimal reaction conditions of 160 ℃ and 0.8 MPa.It is more effective and reusable for the oxidation of cyclohexane than the corresponding unsupported catalyst .
