摘　　要：用新生的勃姆石固载四苯基铁卟啉[Fe TPP/BM]催化剂,用紫外(UV-Vis)、傅立叶红外(FT-IR)和热重分析(TG)技术对该固体催化材料进行结构表征,调查了其催化空气氧化环己烷能力。结果表明:在145℃和0.8 MPa下,此固载四苯基铁卟啉可有效重复催化9次,KA油的收率为7.6%,催化剂转化数为7.6×104,比未固载的四苯基铁卟啉催化产率高40%。The boehmite supported iron tetraphenylporphyrin( FeTPP/BM) was prepared by using a freshly produced boehmite as a support of iron porphyrin,and characterized by the techniques of UV-Visible spectroscopy,Fourier transform infrared spectroscopy and Thermogravimetric analysis,and then used as a catalyst for aerobic oxidation of cyclohexane to cyclohexanol and cycloheanone( KA oil) under the reaction conditions of145oC and 0. 8 MPa. The results indicate that the supported catalyst,can be reused for 9 times for the oxidation, on average,with7.6% of yield( KA oil) and a catalyst turnover number of7.6104. Comparison with the unsupported catalyst,the yields of KA oil for the oxidation over the supported catalyst is elevated to40 %.
