Into an autoclave made of SUS316 having an internal volume of 100 ml were charged above-prepared phenyl benzoate 5.64 g (28.4 mmole), dimethyl carbonate 20 g (222 mmole) and titanium tetraphenoxide 0.13 g (0.30 mmole). The pressure was elevated to 20 kg/cm2 with nitrogen, and then 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 75%, and the yield of diphenyl carbonate was 5%. Furthermore, at the same time, methyl benzoate was produced as a by-product with a yield of 80% (the yield is given in terms of phenyl benzoate)
