Diphenyl carbonate (DPC) was synthesized front CO(2) and phenol catalyzed by Lewis acids. Compressed CO(2) was used as reactant and solvent. It was found that the conversion of phenol and the yield of DPC are dependent on the metal center of Lewis acids, and zinc halides have better catalytic performance than aluminum halides. The reaction of CO(2) with phenol is sensitive to pressure, temperature, and reaction time, and it is improved using triethylamine as acid acceptor. A 31.7% DPC yield was obtained under optimized reaction conditions: 9 MPa at 100 degrees C for 3 h. (C) 2011 Elsevier B.V. All rights reserved.
