AMMONIUM CHLORIDE
Ammonium chloride use
It is mainly used in dry batteries, storage batteries, ammonium salt, leather tanning, electroplating, medicine, photography, electrode, adhesive and so on. Ammonium chloride is also a fast-acting nitrogen chemical fertiliser, containing 24% to 25% nitrogen, is a physiological acidic fertiliser. It is suitable for wheat, rice, corn, rape and other crops, especially Chemicalbook its cotton and linen crops to enhance the toughness of the fibre and tension and improve the quality of the effect. However, due to the nature of ammonium chloride and if the application of the wrong way, often to the soil and crops will bring some adverse effects. Technical conditions: the implementation of the People's Republic of China national standard GB-2946-82.

Other uses and functions
Ammonium chloride is used as an electrolyte in zinc carbon dry cell batteries and in large quantities in the electroplating industry. Especially in cyanide-free plating, ammonium chloride is used more. For example, cyanide-free zinc plating with zinc chloride and ammonium chloride as the main component of the plating solution, zinc chloride and chloride ions in the plating solution to form the ligand ion [ZnCl4]2-(or ZnCl3-) and [Zn(CN)4]2- have similar properties, can be dissociated from a small amount of Zn2+ ions deposited in the cathode plating, so that the plating layer is uniform and dense. As an important raw material for synthesising inorganic polymer compounds. For example, as a superconducting material, the polymeric chain sulfur azide Chemicalbook substance (SN)x is produced by the reaction of S2Cl2 and NH4Cl. Polychlorophosphazene compounds are produced by the reaction of NH4Cl and PCl5, and chloroboronazene compounds are obtained by the reaction of NH4Cl and BCl3. They are all called 'inorganic benzene' compounds, and are a class of non-metallic inorganic materials of great practical value. Others. It can be used as dyeing mordant, analytical reagent, raw material of gunpowder, and often used as soldering flux because ammonium chloride generates chloride with metal oxides, and it is used to remove oxides on the surface of metal when soldering. Ammonium chloride with a content of 99.5 per cent or more can be used as a diuretic.
