The Application of Ammonium Bicarbonate

Ammonium bicarbonate is a white compound with thechemical formula NH4HCO3. It is in the form of granular, plate-like or columnarcrystals and has an ammonia odor. It is a kind of carbonate. Its aqueoussolution is alkaline and unstable. It decomposes into carbon dioxide, ammoniaand water above 36℃ and can be completely decomposed at 60℃. Ammoniumbicarbonate is easily soluble in water and cannot be placed together with acid,because the acid will react with the ammonium bicarbonate to form carbon dioxide,causing the ammonium bicarbonate to deteriorate. In addition, ammoniumbicarbonate can be used as a nitrogen fertilizer, suitable for various soilsand crops, and can provide the nitrogen needed by plants. ‌

1. Used as a nitrogen fertilizer, suitable forvarious soils, and can provide both ammonium nitrogen and carbon dioxiderequired for crop growth, but the nitrogen content is low and easy toagglomerate;

2. Used as an analytical reagent, It is also used to synthesizeammonium salts and degrease fabrics;

3. It can promote crop growth andphotosynthesis, encourage seedlings to grow leaves, and can be used as topdressing, or directly applied as base fertilizer, and used as a food expansionagent;

4. Used as a high grade food fermentation agent . Combined with sodiumbicarbonate, it can be used as a raw material for leavening agents in breads,biscuits, pancakes, etc. It is also used as a raw material for foaming powderedjuice. It is also used for blanching green vegetables, bamboo shoots, etc., aswell as medicine and reagents;

5. Used as buffering agent; aeration agent.

6.Ammonium bicarbonate is widely used in the plastic and rubber industry, potterymaking, chrome tanning and synthetic catalysts.

7. Ammonium bicarbonate has theadvantages of being quick acting, cheap, economical, not hardening the soil,suitable for various crops and soils, and can be used as both base fertilizerand top dressing. It is welcomed by farmers.
