Chemical name: AMmonium bicarbonate E503ii
Molecular Formula: NH4HCO3
Molecular Weight: 98,73
EINECS: 233-786-0
Features and Benefits:Ammonium bicarbonate is a colorless or light-colored compounds, granular, tabular or columnar crystal, 1.57 specific gravity, bulk density of 0.75, compared with ammonium sulfate (0.86) light, slightly heavier than granular urea (0.66), soluble in water, 0 ℃ , the solubility of 11.3%; 20 ℃ when 21%; 40 ℃ to 35% when. Chemical properties of ammonium bicarbonate is not very stable. Thermal decomposition of ammonium bicarbonate is easy to produce ammonia (NH3), water (H2O), carbon dioxide (CO2). Ammonium bicarbonate in water is alkaline reaction. Volatile, with a strong pungent odor. 10 ~ 20 ℃, the easily broken down, 30 ℃ large number of decomposition begins.
Usage:Used as a fertilizer, used as food fermentation agents, expanders, and medicine and reagents.
Packing: 25 kg per bag
Shelf life: 24 months
Storage and transport: Store in a dry, ventilated and pollution-free environment, avoid direct sunlight, and do not stack in the open air. Use as soon as possible after opening.
