The reaction of an organic substrate with phosgene is called phosgenation. Diols react with phosgene to give either linear or cyclic carbonates (R = H, alkyl, aryl): HOCR2−X−CR2OH + COCl2 → 1⁄n [OCR2−X−CR2OC(O)−]n + 2 HCl An example is the reaction of phosgene with bisphenol A to form polycarbonates. WebFeb 27, 2024 · Although phosgene will react with water to produce hydrochloric acid and carbon monoxide (t 1/2 = 0.26 s) (Environmental Protection Agency 2003), its low solubility in water significantly reduces the rate of the reaction and its rapid hydrolysis mitigates the reaction with the mucus layer manifesting its presence with moderate irritation in the …
Phosgene Toxicity: Practice Essentials, Background, …
WebPhosgene. Phosgene is a highly toxic gas produced by the burning of chlorinated hydrocarbons or the action of ultraviolet radiation on such compounds. Phosgene reacts with water to form hydrochloric acid and carbon dioxide. It is considered as an irritant to the skin, eyes and respiratory tract. WebPhosgene reacts with moisture (water or alcohols). In water, it slowly decomposes to hydrochloric acid and carbon dioxide. When heated to decomposition, it will produce toxic and corrosive fumes. Phosgene reacts violently with various chemicals (e.g., alkalis, ammonia, amines, copper, aluminum); it attacks many metals in the small move across country
