Ammonium chloride (referred to as "ammonium chloride", also known as brine, chemical formula: NH4Cl) is a colorless cubic crystal or white crystalline powder. The taste is salty, cool and slightly bitter, acid salt. The relative density is 1.527. Soluble in water and ethanol, soluble in liquid ammonia, insoluble in acetone and ether. The aqueous solution is weakly acidic, and the acidity increases when heated. It starts to volatilize significantly when heated to 100°C, dissociates into ammonia and hydrogen chloride at 337.8°C Chemicalbook, and recombine to form ammonium chloride with extremely small particles when cooled to form a thick white smoke, which is not easy to sink, and is also extremely difficult to dissolve in water. . Heated to 350 ℃ sublimation, boiling point 520 ℃. It has low hygroscopicity, but it can also absorb moisture and agglomerate in wet and rainy weather. It is corrosive to ferrous metals and other metals, especially copper, and has no corrosive effect on pig iron.
Ammonium chloride is a quick-acting nitrogen fertilizer made by the direct action of synthetic ammonia and hydrochloric acid. The nitrogen content is 24-25%. It dissociates chloride ions and ammonium ions in the soil, the latter is absorbed by crops, and the former is combined with hydrogen ions in the soil. into hydrochloric acid, long-term application of ammonium chloride requires additional application of lime.
