Synthesis of Diphenyl Carbonate by Oxidative Carbonylation of Phenol over PdCl2-Mn(OAc)2 Catalyst
Abstract:
The oxidative carbonylation of phenol to diphenyl carbonate catalyzed by Pd-Co, Pd-Cu and Pd-Mn catalyst systems has been studied with the addition of other components such as benzoquinone, Bu2NBr and molecular sieve.The results show that Bu2NBr plays a very important role and Pd Mn catalyst has the highest activity among the three kinds of the catalysts studied.When the reaction is catalyzed by PdMn catalyst at n(PdCl2):n(Mn(OAc)2):n(Bu4NBr):n(benzoquinone)=1:1:10:25, t=100℃, P=2.5 MPa(PCO/PO2=4:1), reaction time 8 h, the yield of DPC is 7.23%.The yield of DPC is found to be increased with increase in total pressure of reactor and could be reached to 10.20% at total pressure of 3.5 MPa.
