ABSTRACT:
Phenolic solutions of 20%-70% by weight of diphenylcarbonate have been found to form a crystalline 1:1 molar adduct of diphenylcarbonate and phenol when allowed to cool to a temperature between about 50.degree. C. and 25.degree. C. Recovery of the crystalline 1:1 molar adduct followed by distillation of phenol therefrom has been found to provide substantially pure diphenylcarbonate.
