Local:
Phosgene (carbonyl dichloride, COCl2) is a very reactive chemical intermediate to prepare isocyanates, chloroformates, isothiocyanates, isonitriles and acid chlorides as well as in the production of polymers including polyurethanes, polycarbonates, and polyureas. Phosgene , however, is extremely toxic gas associated strong safety hazards and handling precautions. It is listed on schedule 3 of the Chemical Weapons Convention. All production sites must be declared to the OPCW. Phosgene is almost entirely in captive consume in the production plant. Chloroformates are relatively less dangerous route to prepare important families of compounds, the carbonates and carbamates. Carbonates are prepared by reaction with alcohol (or phenol) and carbamates are by reaction with an amine ( primary or secondary). Chloroformates are starting materials to prepare carbonate and carbamate derivatives that are used in the pharmaceutical and agrochemical industry.
