What is Diphenyl carbonate?
Chemical properties
white solid
The Uses of Diphenyl carbonate
Estrogenic activity of Diphenyl Carbonate by yeast 2-hybrid assay was studied.
The Uses of Diphenyl carbonate
In the molten state as solvent for nitrocellulose.
Definition
ChEBI: A carbonate ester that is the diphenyl ester of carbonic acid.
Preparation
Diphenyl carbonate is prepared by passing phosgene into a solution of
phenol in aqueous sodium hydroxide in the presence of an inert solvent such
as methylene chloride:
The organic phase, which contains the diphenyl carbonate, is separated; the solvent is stripped off and the diphenyl carbonate is purified by distillation. The reaction is accelerated by tertiary amines and is analogous to the interfacial polycondensation of 2,2-bis(4'hydroxyphenyl)propane and phosgene described. Diphenyl carbonate is a white crystalline solid, m.p. 78??C.
Flammability and Explosibility
Non flammable
Safety Profile
Questionable carcinogen with experimental neoplastigenic and tumorigenic data. When heated to decomposition it emits acrid smoke and irritating fumes
