Phosgene oxime
Phosgene oxime, also known as CX, is a chemical weapon, specifically a nettle agent. It was first produced in 1929. As a solid, it is colorless; as a liquid, it is yellow-brown. It has a strong, irritating odor. The chemical formula for phosgene oxime is CHCl2NO. Additional recommended knowledgeSymptoms of phosgene oxime poisoningPhosgene oxime can be toxic if inhaled, ingested, or absorbed by the skin and the effects of the poisoning occur almost immediately. If inhaled, it irritates the airway and may eventually lead to pulmonary edema, or, literally, drowning in one's own fluids. The effects on the skin include weals, hives, itching, and necrosis of the skin, which scabs and falls off. Absorption through the skin can also lead to pulmonary edema. It also causes lacrimation in the eyes and even blindness. There is no antidote for phosgene oxime poisoning. Generally, any treatment is supportive. The standard decontamination process for humans exposed to CX is to irrigate the eyes and gently wash affected skin with water. If shower facilities are available, these can also be used. Typical physical symptoms are as follows:
This chemical has no useful industrial applications, so accidental exposure is extremely unlikely to occur. Therefore, any exposure to CX is almost certainly the result of its deliberate use as a chemical warfare agent. Chemical propertiesPhosgene oxime is about 70% soluble in water. The boiling point is 128° Celsius (262° Fahrenheit), its melting point is between 35-40° C (95-104°F) Its vapor density is greater than air, which mean it tends to settle in low lying areas. It is corrosive on metals and also decomposes on contact with metals.
