fosgeeni

Fosgeeni, also known as carbonyl dichloride, is a chemical compound with the formula COCl2. At room temperature, it is a colorless gas with a characteristic odor often described as freshly cut hay or grass. It is highly toxic and a potent pulmonary irritant. Fosgeeni is denser than air and can accumulate in low-lying areas.

Historically, fosgeeni was produced on an industrial scale for use as a chemical weapon during World War I due to its severe effects on the respiratory system. Inhalation of even small concentrations can cause delayed but severe pulmonary edema, which can be fatal. Due to its extreme toxicity and the availability of safer alternatives, its use as a chemical weapon has been largely discontinued, and it is listed under Schedule 3 of the Chemical Weapons Convention.

Today, fosgeeni is primarily used in industrial processes, such as the production of plastics, pesticides, and pharmaceuticals. It is an important intermediate in organic synthesis, particularly in the formation of isocyanates and polycarbonates. Its production and use are strictly regulated due to its hazardous nature. Exposure can occur through inhalation, and immediate medical attention is crucial for anyone suspected of exposure.
