Product 1

HCID 7597Diphenyl carbonate

Procedure

The above procedure is repeated except that hydrolysis of the tetraphenyl orthocarbonate is effected by adding to a solution of 10.5 grams of phenol in 4.0 ml. of 0.1N aqueous sulfuric acid. The reaction is complete within two hours. An excellent yield of diphenyl carbonate is obtained and no significant by-products are formed.
