- Diphenyl carbonate is an organic chemical
compound. It is both as a monomer in combination with bisphenol A in
the production of polycarbonate polymers and a product of the
decomposition of polycarbonates.
- DPC is produced in two steps: phenol and
DMC react to form phenylmethyl carbonate (PMC), followed by PMC
disproportionation to DPC.
- The diphenyl carbonate is prepared by
reacting dimethyl carbonate with phenol, so no phosgene is used as
in the earlier process.
- Early commercial production of
polycarbonate employed reacting phosgene with phenol to produce
diphenyl carbonate, a high boiling liquid that was then reacted with
bisphenol A to produce the polymer and liberate phenol for reuse.
- The transesterification process using
diphenols and diphenyl carbonate (DPC) has been given more
recognition instead of the interfacial polycondensation of diphenols
with phosgene, because of advantages like no toxic phosgene, no
solvent, and no salt formation.
- Diphenyl carbonate (DPC) is a key
rawmaterial for producing aromatic polycarbonates. It is still
mainly synthesized by using severely toxic phosgene as a raw
material.
- Diphenyl Carbonate is a precursor in the
production of Polycarbonate (PC). Polycarbonate is widely employed
as an engineering plastic important to the modern lifestyle; used
in, for example, the manufacture of electronic appliances, office
equipment and automobiles.

- Production is expected to increase by
around 6% per year at least until 2010 with the fastest regional
growth expected in East Asia, averaging 8.7% per year through 2009.
- There is increasing demand for a safer and
environmentally favorable process for DPC production. In recent
years, some porous carriers, such as active carbon, molecular sieve,
porous alumina and the like, have been used in the synthesis of DPC,
however, the yield of DPC is less than 6.2%.
