Ammonium acetate is a chemical compound with the formula NH4CH3COO (sometimes written as CH3COONH4).
Contents
Properties
Chemical
Ammonium acetate decomposes at temperatures above 165 °C to yield acetamide:
- CH3COONH4 → CH3C(O)NH2 + H2O
If heated further, it will convert to acetonitrile (methyl cyanide).
Physical
Ammonium acetate is a white hygroscopic solid. Ammonium acetate is volatile at low pressures.
Availability
Ammonium acetate can be purchased online cheaply.
Preparation
Ammonium acetate can be prepared by reacting acetic acid with ammonia, ammonium bicarbonate or carbonate. Drying the solution by boiling the excess water is difficult, as ammonium acetate will decompose. The best way to synthesize it is to bubble ammonia gas into anhydrous (glacial) acetic acid, causing the ammonium acetate to crystallize, though this is expensive.
Projects
- Acetamide synthesis
- Acetonitrile synthesis
Handling
Safety
Ammonium acetate is non-toxic, though if heated it can generate acetamide which is considered carcinogenic.
Ammonium acetate is hygroscopic and will slowly hydrolyze to yield acetic acid, which is irritant and corrosive in large quantities.
Storage
Should be stored in dry sealed containers, as it's hygroscopic.
Disposal
Ammonium acetate is a harmless source of nitrogen to organic life and can be discarded without any special treatments.
