Producing, or produced by, the action of light; -- used specifically to designate a gas also called carbonyl chloride. See Carbonyl.
A reactive chemical substance (COCl2), also called carbonyl choride, used in synthesis of numerous substances. In the First Worlds War it was also used as a poisonous gas in combat.
A colorless to light yellow gas. Uses include pesticide and herbicide manufacture, dyes, production of isocyanates, and organic carbonates. Hazards: Highly toxic, symptoms include burning eyes, vomiting, and chest pain.
Carbonyl chloride, a chemical warfare agent used in World War I (was leading cause of death). Causes severe pulmonary irritation and injury.
a colorless poisonous gas that smells like new-mown hay; used in chemical warfare
An anti-gas instructional officer; empty talk; profanity.
Phosgene is a colorless gas with an odor of newly mown hay. Phosgene has a density that allows it to stay in the air and low-lying places for fairly long periods of time. It is easy to produce but is highly unstable in storage.
Carbonyl chloride; a colorless liquid below 8.2°C, but an extremely poisonous gas at ordinary temperatures; it is an insidious gas, since it is not immediately irritating, even when fatal concentrations are inhaled.
chemical formula COCl2, phosgene is a very toxic gas with a TLV of 0.1ppm. Phosgene has a moldy, hay like odor and is irritating. Phosgene is a reaction product that can form during chlorinated furnace cleans if sufficient oxygen isn't present.
Phosgene is the chemical compound with the formula COCl2. It is also known as carbonyl chloride, or its military designation CG. This highly toxic gas gained infamy as a chemical weapon during World War I, but is also a valuable industrial chemical.
