Ammonium Acetate


Synonyms: acetate of ammonia

Chemical formula: CH3COONH4

International name: AMMONIUM ACETATE

CAS No.: 631-61-8

Grade: import, pure, GOST 3117-78

Appearance: white hygroscopic crystals

Ammonium acetate (acetate of ammonia) is a colorless crystalline mass consisting of extremely hygroscopic small needle-shaped crystals. At a temperature above 144°C, the reagent undergoes decomposition forming acetamide: NH4CH3COO = CH3CONH2 + H2Ob. It is very soluble in water (58.6% at 4°С), soluble in ethyl alcohol.


Ammonium acetate is a chemical compound with a composition NH4C2H3O2, can be obtained by reaction of acetic acid with ammonia. In laboratory conditions, ammonium acetate can be obtained as follows: add 10% NH4OH solution to 80% CH3COOH under cooling water and vigorous mixing until the solution has a strong odor of ammonia. Filter the solution, if required, evaporate using water bath until appearing crystal film. Aspirate crystals precipitated using Buchner funnel and immediately transfer to tightly closed can.


Ammonium acetate is available, relatively cheap and widely used as follows:

  • in analytical chemistry,
  • in organic synthesis,
  • as a component of buffer solutions,
  • as a mordant when dyeing wool,
  • in food industry as a preservative, food additive, etc.
