WebApr 5, 2024 · Thus, we can distinguish between ethylamine and aniline by using azo dye test. Aniline is an aromatic amine and ethyl amine is aliphatic amine. Aniline reacts with nitrous acid at low temperature; it forms benzene diazonium chloride (a diazo salt). Nitrous acid is prepared in situ by the reaction of sodium nitrite on dilute hydrochloric acid.
