1.Physical and chemical properties Formula:NH4HCO3 Molecular weight:79.06 Appearance:white monoclinic, orthorhombic crystal or irregular crystal, solid powder or granules in normal state. Density:1.573 The mass fraction of nitrogen in pure ammonium bicarbonate is about 17.72% Ammonium bicarbonate is apt to decomposition, and the decomposers include ammonia, water, and carbon dioxide. When the ambient temperature is below 10 ?, it is chemically stable, and does not decompose basically; the decomposition is not significant at 10-20°C; when the temperature is 30°C or more, it decomposes significantly. The greater the humidity and/or the temperature are, the faster the decomposition. Soluble in water, alcohol, and acetone, and the aqueous solution is alkaline. 2.Uses As a kind of neutral fertilizer, it is suitable for all kinds of soils and crops, which can be used as base fertilizers and top dressing. The long-term use of it does not make the soil compact; both ammonium nitrogen and carbon dioxide needed by crops for growth are provided. It can be used as the raw materials for producing potassium carbonate and reagents carbonate through the ion exchange method; it is also the foaming agent for foam rubbers. Extraction agents for vitamin B1 used in the pharmaceutical industry, and the amine treatment agent for the intermediate benzene acid of ampicillin; Tanning buffers in the leather industry; Ammonium fluoride etchants for frosted bulbs in the bulb industry It can also be used in the area of food fermentation, where it mainly serves as high-end food fermentation agents; being combined with sodium bicarbonate, it can be used as leavening agents for cakes, biscuits and other raw materials, or raw materials for foam juices, refrigeration perm lotion and electrolyte; it can also be used as fire extinguishing agents, or the auxiliary raw materials for producing phosphors. ?
