Ammonium Carbonate Information. Ammonium carbonate, (NH4)2CO3, is an unstable inorganic salt, melting ( 1) at 43˚c. Commercial "ammonium carbonate" is partly, or entirely, composed of an ammonium bicarbonate / ammonium carbamate mixture, NH4HCO3 / NH2CO2NH4. It is a white solid, which tends to give off fumes of ammonia in air.

commercially feasible. The Merseburg Process for manufacturing ammonium sulfate from gypsum is based on the chemical reaction between gypsum and ammonium carbonate. Ammonium carbonate is formed by the reaction of ammonia and carbon dioxide in aqueous solution. The reaction produces insoluble calcium carbonate and an ammonium sulfate solution.
historical use of the Merseburg process and studies conducted by the Tennessee Valley Authority, a preliminary flow diagram for the production of ammonium sulfate fertilizer from FGD-gypsum was developed. The major equipment for the process includes an absorption tower, the gypsum converter, a concentrator and two

Ammonium carbonate was of purity pro analysis (LACH-NER, CZ). The concentration of ammonium carbonate in water solution during experiment was determined by the addition of 1 M HCl and back titration with 1 M NaOH using methyl red as an indicator. Experiments were carried out at the temperatures of 20, 30, 40, and 50 °C.
