APPLICATIONS |
||
|
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.
Butyl Chloroformate is used as an Intermediate for the production of peroxide chemicals, dyes, crop protection chemicals and pharmaceuticals. |
