Preparation of Catalyst Supported by CuO-CoO-MnO/SiO2 Nanocomposlte Aerogel and Its Catalytic Performance In the Synthesis of Diphenyl Carbonate

摘要

A novel catalyst supported by nano-porous CuO-CoO-MnO/Si02 composite aerogel was prepared by impregnation method. It was used in the catalytic synthesis of diphenyl carbonate (DPC). The effects of temperature, pressure and reaction time on the yield of DPC were investigated. The results show that Phenol and DPC can smoothly pass through the nano-pores of the composite aerogel during the catalytic synthesis of DPC. When the temperature, pressure and reaction time of DPC synthesis are 110 °C, 6.0 MPa and 6 h, respectively, the yield of DPC is 27.14 mass%, which is much higher than that of catalysts supported by other porous carriers.
