1、Chemical Name: Sodium Chloride
2、Molecular Formula : NaCl
3、Molecular Weight: 58.44
4、CAS: 7647-14-5
5、Character: It is white and odorless crystal powder. Melting point is 801℃,boiling point is 1465℃, it is slightly soluble in ethanol, propyl alcohol and butane. It becomes plasma when soluble in butane. It is easily soluble in water, the solubility is 35.9g(room temperature).NaCl forms colloid when dispersing in ethanol, the solubility decrease because of the hydrogen chloride, it is hardly soluble in concentrated hydrochloric acid. It is deliquescent and tastes salty. It is easily soluble in water, soluble in glycerin, hardly soluble in ethyl ether.
6、Usage: It is used as salt in food and fishery, it also can be used as the raw material of seasoning and table salt.
7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substance.
