difenilkarbonát

Diphenyl carbonate is an organic compound with the chemical formula (C6H5O)2CO. It is a carbonate ester formed from phenol and phosgene. At room temperature, it is a white solid with a low melting point. Diphenyl carbonate is a key intermediate in the production of polycarbonate plastics. It is typically synthesized through the reaction of phenol with phosgene or through a transesterification process involving dimethyl carbonate and phenol.

The primary application of diphenyl carbonate is as a monomer in the synthesis of bisphenol A polycarbonate. This polymerization process involves reacting diphenyl carbonate with bisphenol A, producing polycarbonate and phenol as a byproduct. This method is favored in some regions due to environmental concerns associated with phosgene. Diphenyl carbonate also finds use in the production of other polymers and as a solvent in certain chemical reactions. Its stability and reactivity make it a valuable component in various industrial processes.
