Diazotisation and the Azo Dye Test
With hydrochloric acid, sodium nitrite forms nitrous acid in the reaction mixture, which converts aniline into benzenediazonium chloride; the reaction is run at 0–5 °C because the diazonium salt decomposes when warm. Added to alkaline 2-naphthol, the cold diazonium solution couples to an orange-red azo dye, the standard test for a primary aromatic amine.
Nitrite or Nitrate?
Dilute acid alone releases brown fumes from a nitrite in the cold, whereas a nitrate gives none until concentrated sulphuric acid is used.
Related Reagents for Diazotisation
- Aniline — the primary aromatic amine used in diazotisation practicals.
- Hydrochloric Acid Dilute — acid that turns sodium nitrite into nitrous acid.
- Sodium Nitrate — the nitrate salt it is compared with in anion tests.
The full reagent range is in Chemistry Lab.
