Phosgene csb
WebPhosgene (CG) reacts with alcohols and ammonia. Above 572°F (300°C), phosgene (CG) decomposes in the presence of moisture to form hydrochloric acid and carbon dioxide. In the presence of moisture, phosgene (CG) attacks plastic, rubber, and many metals. Phosgene is not combustible. Containers may explode when heated. Webphosgene under pressure can cause frostbite as well as severe irritation and corrosive effects. Children are more vulnerable to toxicants affecting the skin because of their relatively larger surface area:body weight ratio. Ingestion ; Ingestion of phosgene is unlikely because it is a gas at room : temperature.

WebPhosgene, as the formal carboxylic acid dichloride of carbonic acid, is a highly reactive reagent, which affords high turnovers and good yields. Thus, both symmetrical and unsymmetrical dicarbonates, the latter via chloroformates, can easily be produced. WebPhosgene is a colorless, fuming liquid below 47° (8.2°) and a colorless, nonflammable gas above 47°. At low concentrations, its odor is similar to that of green corn or new mown hay; at high concentrations, its odor can be sharp and suffocating. Phosgene is slightly soluble in water and is hydrolyzed slowly by moisture to form hydrochloric acid.
