Ammonium bicarbonate,food gradeFormula: NH4HCO3M.W.: 79.06Synonyms: Ammonium hydrogen carbonate; Ammonium acid carbonate CAS No.: 1066-33-7Description:Colorless crystals or whitecrystalline powder, soluble in water, insoluble in alcohol and acetone, aqueous solution appears alkali, specific gravity 1.58,melting point 107.5ºC.Ammonium bicarbonate is a white, crystalline powder with a slight odour of ammonia that can dissolve in water to give a mildly alkaline solution. It is however insoluble in acetone and alcohols. Ammonium bicarbonate decomposes at 36 to 60 °C into ammonia, carbon dioxide and water vapor in an endothermic process (as it is with many ammonium salts) and so causes a drop in the temperature of the water. When reacted with acids, carbon dioxide is produced, while reactions with alkalis give ammonia.Specifications:ItemsIndexsTotal alkali NH4HCO3 wt%99.2-101.0Chloride Cl wt% max0.003Sulphate SO4 wt% max0.007Ash wt% max0.008As wt% max0.0002Heavy metals Pb wt% max0.0005Usege:Be used as high-grade food fermentation agent.
