| Products name: | Ammonium Chloride |
| CAS NO.: | 12125-02-9 |
| Type of: | 53.49 |
| Chemical formula: | NH4Cl |
| Common Name: | Electricity Salt, Electrical powder, Good Salt |
| Nature: | Colorless cubic crystal or white crystalline powder. The taste is salty and slightly bitter, soluble in water and acidic, and the pH is generally around 5.6. The relative density is 1.527. Soluble in water, slightly soluble in ethanol, soluble in liquid ammonia, insoluble in acetone and ether. When heated to 100 ° C, it begins to volatilize significantly. At 337.8 ° C, it dissociates into ammonia and hydrogen chloride. When it is cooled, it recombines to form ammonium chloride with very small particles. It is white smoke, not easy to sink, and it is not easy to dissolve again in water. Heat to 350 ° C sublimation, boiling point 520 ° C. It has low hygroscopicity, but it can also absorb moisture and agglomerate in wet and rainy weather. Powdered ammonium chloride is very easy to absorb moisture, especially wet ammonium. The moisture absorption point is generally about 76%. When the relative humidity in the air is greater than the moisture absorption point, ammonium chloride produces moisture absorption and is easy to agglomerate. The aqueous solution is weakly acidic and the acidity is enhanced upon heating. It is corrosive to ferrous metals and other metals, especially to copper, and has no corrosive effect on pig iron. At present, there are two main production processes for this product: one is to use the Hou's alkali method invented by the famous Chinese scientist Hou Debang, and to produce both soda ash and ammonium chloride; the second is to produce a by-product of potassium salt such as potassium carbonate. Ammonium chloride is easy to agglomerate and is usually added by an anti-caking agent to prevent product agglomeration. |
