| | Diphenyl carbonate Usage And Synthesis |
| Chemical Properties | white solid | | Uses | In the molten state as solvent for nitrocellulose. | | Uses | Estrogenic activity of Diphenyl Carbonate by yeast 2-hybrid assay was studied. | | 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. | | Definition | ChEBI: A carbonate ester that is the diphenyl ester of carbonic acid. | | Flammability and Explosibility | Nonflammable | | Safety Profile | Questionable
carcinogen with experimental neoplastigenic
and tumorigenic data. When heated to
decomposition it emits acrid smoke and
irritating fumes |
