Synthesis of ammonium bicarbonate

Preparation of ammonium bicarbonate

Preparation of ammonium bicarbonate from ammonium carbonate

Preparation of ammonium bicarbonate from ammonium carbonate

Ammonium bicarbonate is most readily obtained by dissolving commercial ammonium carbonate in water at 50° C and treating it with carbon dioxide while cooling. The delivery tube for the carbon dioxide must be moderately wide to prevent clogging. Filter the crystalline mass of bicarbonate which has separated out, on a Buchner funnel at once, and dry for several days in a desiccator over sulfuric acid.

Ammonium bicarbonate may also be prepared by passing carbon dioxide into a flask containing concentrated ammonia water (sp. gr. 0.900) while cooling the flask with running water.

Preparation of ammonium bicarbonate from ammonium hydroxide

Preparation of ammonium bicarbonate from ammonium hydroxide

The ammonium crystallizes out from the solution. Neither of these methods yields a product entirely free from carbonate.

Ammonium bicarbonate is quite soluble in water. The solution loses carbon dioxide at ordinary temperatures or on standing in the air. The dry salt is stable and odorless, but at 60° C. decomposes into ammonia, water, and carbon dioxide.
