Diphenyl carbonate (also known as diphenyl carbonate is) an organic - chemical compound . At room temperature it is a white, almost odorless solid.

Manufacturing

Diphenyl carbonate is obtained industrially by transesterification of dimethyl carbonate with phenol . However, numerous other methods are known with which diphenyl carbonate can be produced, such as the direct oxidative carbonylation of phenol with carbon dioxide or the transesterification of dialkyl oxalates with phenol.

use

Diphenyl carbonate is mainly used in the production of polycarbonates . A transesterification with bisphenol A takes place . This reaction is of particular interest because it avoids the use of the highly toxic phosgene .
