Into an autoclave made of SUS316 having an internal volume of 100 ml were charged the above-produced phenyl benzoate 30 g (151 mmole), dimethyl carbonate 6.82 g (75.7 mmole) and titanium tetraisopropoxide 0.43 g (1.51 mmole). The pressure was elevated to 20 kg/cm2 with nitrogen, and the contents were reacted for three hours at 150° C. After completing the reaction, the reaction mixture was analyzed by gas chromatography. As a result, the yield of methyl phenyl carbonate was 19%, and the yield of diphenyl carbonate was 21%. Furthermore, at the same time, methyl benzoate was produced as a by-product with a yield of 40% (the yield was based on phenyl benzoate).
