Sodium chloride is an ionic compound, chemical type NaCl, colorless cubic crystal or small crystalline powder, salty.It has a white crystalline appearance and is mainly derived from sea water, which is the main ingredient of table salt.Soluble in water, glycerin, slightly soluble in ethanol (alcohol), liquid ammonia;Insoluble in concentrated hydrochloric acid.Impure sodium chloride is deliquescent in air.[1] is a good stability, its aqueous solution is neutral, industry generally adopt the method of electrolytic saturated sodium chloride solution to produce hydrogen, chlorine and caustic soda (sodium hydroxide) and other chemical products (commonly known as chlor-alkali industry) can also be used for ore smelting, electrolysis of molten sodium chloride crystal lively sodium metal production), medical used to configure the physiological saline, life can be used for flavoring.

 

Physical Property:
Sodium chloride is a white odorless crystalline powder.Melting point 801ºC, boiling point 1465ºC, slightly soluble in ethanol, propanol, butane, after the butane and become plasma, soluble in water, water solubility of 35.9g (room temperature).NaCl dispersed in alcohol can form colloids, its solubility in water is reduced due to the presence of hydrogen chloride, almost insoluble in concentrated hydrochloric acid.No smell and salty, easy to be deliquescent.Soluble in water, soluble in glycerol, almost insoluble in ether.

Application:
1. Industrial:
   (1) electrolytic sodium chloride solution, will produce hydrogen and chlorine gas, chlorine gas has a wide range of applications in chemical industry, can be used in the synthesis of PVC, insecticide, hydrochloric acid, etc
   (2) When the process of sodium metal: through electrolysis molten sodium chloride and calcium chloride mixture to produce sodium metal.Calcium chloride as a flux can reduce the melting point of sodium chloride below 700ºC.Calcium is less reductive than sodium and does not introduce impurities.
  (3) Sodium chloride is necessary for many biological reactions. For example, a variety of solution formulations in molecular biological experiments contain sodium chloride, and most bacterial culture media contain sodium chloride.At the same time, it is also the raw material for making soda ash with ammonia.
  (4) Inorganic and organic industries are used as raw materials for the manufacture of caustic soda, chlorates, hypochlorates, bleaches, refrigerants for refrigeration systems, raw materials for organic synthesis and salting out agents.The steel industry is used as a heat treating agent.High temperature heat source with potassium chloride, barium chloride and other salt bath, can be used as a heating medium, so that the temperature maintained between 820 and 960ºC.In addition, also used in glass, dye, metallurgy and other industries.
 (5) Analytical reagent used for trace analysis of fluorine and silicate
2.Food Industry
The food and fisheries industries are used for salting, as well as as raw materials for seasonings and refined table salt
