Phosgene reaction with water
WebPhosgene is a stable compound at normal ambient temperatures (21oC or 70oF). At temperatures above 250oC (482oF), phosgene decomposes to form mixtures of carbon … WebIn water, phosgene is sparingly soluble and decomposes to hydrochloric acid and carbon dioxide. It also reacts with ethanol but is soluble unaltered in benzene, toluene, most liquid hydrocarbons, and in glacial acetic acid. Phosgene decomposes on heating above 300 °C producing chlorine and carbon monoxide.

WebPhosgene reacts with water in the lungs to form hydrochloric acid, the main damaging chemical (Borak and Diller, 2001). Chlorine reacts with water inside the lungs to form hypochlorous acid that causes severe damage to lung tissue. Chloropicrin is a milder and non-lethal chemical that irritates the mucous membrane (Pesonen and Vähäkangas, 2024). WebIt is volatile and reacts with water to form carbonyl sulfide (COS) and two molecules of hydrogen chloride. The carbonyl sulfide then reacts with another water molecule to form hydrogen sulfide and carbon dioxide ( Figure 90.3 ). Thiophosgene has two reactive sites associated with the carbon atom.

WebIn relative terms, phosgene is slow to hydrolyze when exposed to water whereas other halogen compounds tend to react very quickly with water. This characteristic represents a key understanding for emergency response and HAZMAT personnel’s awareness. Systems handling phosgene need to be properly designed, constructed and maintained. WebIf phosgene oxime gas is released into the air, people can be exposed through skin contact or eye contact. They may also be exposed by breathing air that contains phosgene oxime. If phosgene oxime liquid is released into water, people can be exposed by touching or drinking water that contains phosgene oxime.
