Ammonium Bicarbonate
Basic Information
Name: Ammonium Bicarbonate
Other names: Ammonium hydrogen carbonate; ammonium acid carbonate
Molecular formula: NH₄HCO₃
Molecular weight: 79.06
CAS number: 1066-33-7
2.Physical and Chemical Properties
- Appearance: White crystalline powder with a slight ammonia odor
- Melting point: Decomposes at approximately 36–60 °C (releasing ammonia, carbon dioxide and water)
- Density: Approximately 1.58 g/cm³
- Solubility: Soluble in water (about 21.6 g/100 mL at 20 °C); slightly soluble in ethanol
- Stability: Unstable; decomposes on heating and slowly in moist air
3.Main Functions and Applications (What are its uses?)
- Food (core application): Used as a leavening agent for biscuits, bread and cakes, and as an acidity regulator (E503).
- Agriculture: A nitrogen fertilizer containing about 17.7% nitrogen.
- Industrial: Applied as a foaming agent for rubber and plastics, and as a flame retardant.
- Fermentation industry: Used as a fermentation promoter. Pharmaceutical: Serves as an expectorant raw material and pH regulator. Water treatment: Used for pH adjustment and buffering.
- Analytical chemistry: Employed as a buffer.
4.A Benchmark-Level Industrial Masterpiece - A Meticulously Crafted "Food-Grade" Leavening Agent!
Total alkalinity reaches 99.2% or higher, meeting the premium grade and delivering reliable leavening performance. Low chloride, sulfate, non-volatile residue, arsenic and heavy metals ensure food-grade safety and purity.
Clean decomposition leaves no residue, making it ideal for food leavening and fermentation applications. "What you see is what you get" - every lot ships with a complete certificate of analysis.
