Ammonium acetate is a chemical compound with the formula NH4CH3COO (sometimes written as CH3COONH4).

PropertiesEdit

ChemicalEdit

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).

PhysicalEdit

Ammonium acetate is a white hygroscopic solid. Ammonium acetate is volatile at low pressures.

AvailabilityEdit

Ammonium acetate can be purchased online cheaply.

PreparationEdit

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.

ProjectsEdit

HandlingEdit

SafetyEdit

Ammonium acetate is non-toxic, though if heated it can generate acetamide which is considered carcinogenic.

StorageEdit

Should be stored in dry sealed containers, as it's hygroscopic.

DisposalEdit

Ammonium acetate is a harmless source of nitrogen to organic life and can be discarded without any special treatments.
