Ammonium chloride

Products Description of Ammonium chloride CAS#：12125-02-9

Ammonium chloride (referred to as "chloramine", also known as sal ammoniac, chemical formula: NH₄Cl) is a colorless cubic crystal or white crystalline powder. It has a salty and slightly bitter taste and is classified as an acid salt. With a relative density of 1.527, it is soluble in water, ethanol, and liquid ammonia but insoluble in acetone and ether. Its aqueous solution is weakly acidic, and the acidity intensifies upon heating. When heated to 100 °C, it starts to volatilize significantly; at 337.8 °C, it dissociates into ammonia and hydrogen chloride. Upon cooling, these two gases recombine to form fine ammonium chloride particles, producing white smoke that is not easily settled and highly insoluble in water. It sublimes at 350 °C and boils at 520 °C. Ammonium chloride has low hygroscopicity but can absorb moisture and cake in humid or rainy weather. It is corrosive to ferrous metals and other metals—particularly highly corrosive to copper, yet non-corrosive to cast iron. Ammonium chloride can be prepared via the neutralization reaction of ammonia with hydrogen chloride gas or hydrochloric acid (reaction equation: NH₃ + HCl → NH₄Cl). When heated, it decomposes into ammonia and hydrogen chloride (reaction equation: NH₄Cl → NH₃ + HCl), and this reaction proceeds unidirectionally to the right only in an open system.

Product Application of Ammonium chloride CAS#：12125-02-9

Ammonium chloride is mainly used for dry batteries, storage batteries, ammonium salts, tanning, plating, medicine, photography, electrodes, adhesives, etc. Ammonium chloride is also an available nitrogen chemical fertilizer whose nitrogen content is 24% to 25%. It is a physiological acidic fertilizer and suitable for wheat, rice, corn, rapeseed and other crops. It have the effects of enhancing fiber toughness and tension and improving quality especially for cotton and linen crops. However, due to the nature of ammonium chloride, if the application is not right, it will bring some adverse effects to soil and crops.
Technical conditions: the implementation of the People's Republic of China national standard GB-2946-82.
