Anwendungen & Verwendung
Verwenden
Ammonium acetate is used in the manufacture of acetamide and as a diuretic and diaphoretic in medical applications. The wool industry also uses this salt as a dye mordant. Buffer solution; determination of lead and iron; separating lead sulfate from other sulfates.
Herstellung & Synthese
synthetische
Ammonium acetate is manufactured by neutralizing acetic acid with ammonium carbonate or by passing ammonia gas into glacial acetic acid. Acidic ammonium acetate, CH3CO2NH4.CH3CO2H[25007-86-7], is manufactured by dissolving the neutral salt in acetic acid.
