Main types and grades:
1. Ammonium Carbonate USP Pharmaceutical Grade
Carbonic acid, monoammonium salt, mixture with ammonium carbamate.
Monoammonium carbonate mixture with ammonium carbamate [8000-73-5].
Packaging and storage: Preserve in tight, light-resistant containers, at a temperature not above 30C.
Identification: When heated, it is volatilized without charring, and the vapor is alkaline to moistened litmus paper. A solution (1 in 20) effervesces with acids.
Residue on ignition: not more than 0.1%.
Chloride: Maximum 0.0035%.
Sulfate: A 2.0-g portion shows no more sulfate than corresponds to 0.10 mL of 0.020 N sulfuric acid (0.005%).
Heavy metals: the limit is 0.001%.
Assay: Meet the requirements.
2. Ammonium Carbonate FCC Food Grade
Ammonium Carbonate (NH4)2CO3, Crystal Ammonia occurs as a white powder or as hard, white or translucent masses.
When exposed to the open air, Ammonium Carbonate (NH4)2CO3, Crystal Ammonia will turn opaque and is finally converted into porous lumps or a white powder of ammonium bicarbonate because of the loss of ammonia and carbon dioxide
Function: as Buffer; as leavening agent or neutralizing agent.
3. Ammonium Carbonate ACS AR Analytical Reagent Grade.
