HCID 18475Oxalic acid, diphenyl ester

Procedure

400 parts of an aqueous solution of sodium hydrogencarbonate having a pH of 8 were added to 200 parts of diphenyl carbonate, obtained through the decarbonylation reaction of diphenyl oxalate using tetraphenyl phosphonium chloride as a catalyst, and the mixture was heated to 90° C. and stirred for 1 hour to obtain diphenyl carbonate containing 1.3 ppm of hydrolyzable chlorine.
