WebPhosgene is a widely used chemical intermediate, primarily manufactured in the preparation of many organic chemicals. Phosgene is used for the synthesis of isocyanate-based … 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. See more Phosgene is the 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. It can be thought of as formaldehyde with … See more Phosgene is a planar molecule as predicted by VSEPR theory. The C=O distance is 1.18 Å, the C−Cl distance is 1.74 Å and the Cl−C−Cl angle is 111.8°. Phosgene is a See more Phosgene was synthesized by the Cornish chemist John Davy (1790–1868) in 1812 by exposing a mixture of carbon monoxide and chlorine to See more Phosgene is an insidious poison as the odor may not be noticed and symptoms may be slow to appear. The odor detection threshold for phosgene is 0.4 ppm, four … See more Industrially, phosgene is produced by passing purified carbon monoxide and chlorine gas through a bed of porous activated carbon, which serves as a catalyst: CO + Cl2 → COCl2 (ΔHrxn = −107.6 kJ/mol) See more The reaction of an organic substrate with phosgene is called phosgenation. Synthesis of carbonates Diols react with phosgene to give either linear or cyclic carbonates (R = H, alkyl, aryl): HOCR2−X−CR2OH + … See more • The first major phosgene-related incident happened in May 1928 when eleven tons of phosgene escaped from a war surplus store in central Hamburg.
