Chemical Properties
white solid
Uses
Estrogenic activity of Diphenyl Carbonate by yeast 2-hybrid assay was studied.
Uses
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
