About this 3D model

From Wikipedia, the free encyclopedia "COCl2" redirects here. For the compound CoCl2, see Cobalt(II) chloride . Not to be confused with phosphine , phosphene , oxalyl chloride , or phosgene oxime . Phosgene is an organic chemical compound with the formula COCl2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut hay or grass. [7] It can be thought of chemically as the double acyl chloride analog of carbonic acid , or structurally as formaldehyde with the hydrogen atoms replaced by chlorine atoms. Phosgene is a valued and important industrial building block, especially for the production of precursors of polyurethanes and polycarbonate plastics. Phosgene is extremely poisonous and was used as a chemical weapon during World War I , where it was responsible for 85,000 deaths . It is a highly potent pulmonary irritant and quickly filled enemy trenches due to it being a heavy gas. It is classified as a Schedule 3 substance under the Chemical Weapons Convention . In addition to its industrial production, small amounts occur from the breakdown and the combustion of organochlorine compounds , such as chloroform . [8] Print modell for educational use.
