Description
A colorless, poisonous gas with a suffocating odor. Phosgene can be formed as a decomposition product of chlorinated hydrocarbons with heat or ultraviolet light. It can be detected using a solution of p-dimethylaminobenzaldehyde (5%) and diphenyl amine (5%) in ethanol. A paper soaked in this mixture then dried will turn from yellow to deep orange in the presence of less than 1 ppm phosgene.
Synonyms and Related Terms
