Classification:
HS CODE: 2827109000, CAS NO.: 12125-02-9
Key words:
Ammonium chloride
Product Description
1. Nature:Ammonium chloride is a colorless crystalline or white crystalline powder, easily soluble in water, slightly soluble in ethanol, soluble in liquid ammonia, and insoluble in acetone and ether. The aqueous solution is weakly acidic, and the acidity increases upon heating. It is corrosive to ferrous metals and other metals, especially more corrosive to copper, with no corrosive effect on cast iron. Production and acceptance are organized according to industry standard GB/T2946-92, with the main ammonium chloride content reaching over 99.3%, and other contents meeting or exceeding standard requirements, with a product quality rate of 100%.
2. Uses:Mainly used in dry batteries, storage batteries, ammonium salts, tanning, electroplating, precision casting, medicine, photography, electrodes, adhesives, yeast nutrients, and dough improvers, etc.
3. Packaging:Each bag contains 25Kg or 50Kg lined with a plastic bag, with an outer woven bag.
