Ethyl chloroformate Chemical Properties,Usage,Production

Chemical Properties
Colorless to yellow liquid
Cathyl Chloride is used in the preparation of new inhibitors for β-homocysteine S-methyltransferase. Also used in the synthesis of a hexosaminidase inhibitor.
General Description
A colorless liquid with a pungent odor. Flash point 66°F. Very toxic by inhalation. Corrosive to metals and tissue. Vapors are heavier than air. Prolonged exposure to low concentrations or short exposure to high concentrations may have adverse health effects from inhalation.
Air & Water Reactions
Highly flammable. Emits fumes containing HCl on contact with moist air. Decomposes exothermically but slowly in water.
Reactivity Profile
Ethyl chloroformate decomposes slowly in water to form ethanol, HCl, and CO2 Attacks many metals especially in humid atmosphere [Handling Chemicals Safely 1980. p. 476]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
Health Hazard
Inhalation causes mucous membrane irritation, coughing, and sneezing. Vapor causes severe lachrymation; liquid causes acid-type burns of eyes and skin, like those of hydrochloric acid. Ingestion causes severe burns of mouth and stomach.
Fire Hazard
Special Hazards of Combustion Products: Toxic chlorine and phosgene gases may be formed in fires.
