N-Nitrosodiphenylamine Use and Manufacturing

Methods of Manufacturing

It is derived from the reaction of diphenylamine and sodium nitrite in the presence of sulfuric acid. The nitrosation reaction uses ethanol or xylene (or chlorobenzene) as the solvent, and the concentration of the sodium nitrite solution is 40%. The sulfuric acid concentration is 30% and it reacts at about 26°C for 2.5-3 hours. The reaction was washed with water to pH=6-7. When ethanol solvent is used, solid product N-nitrosodiphenylamine is obtained after drying; when xylene or chlorobenzene is used as a solvent, a liquid product is obtained, and after drying with calcium chloride, a liquid product is obtained.

Uses

N-Nitrosodiphenylamine is the N-nitroso analogue of diphenylamine that was once used as a rubber additive but is no longer due to undesirable side effects. N-Nitrosodiphenylamine may have potential carcinogenic activity and is currently classified as a probable carcinogen by EPA.
