Industry grade Sodium chloride powder CAS 7647-14-5

Industry

1. Electrolysis of sodium chloride aqueous solution produces hydrogen and chlorine. Chlorine is widely used in the chemical industry and can be used in the synthesis of polyvinyl chloride, pesticides, hydrochloric acid, etc.
2. Sodium chloride powder is required for many biological reactions. For example, in molecular biology experiments, various solution formulations contain sodium chloride, and most bacterial culture media contain sodium chloride. It is also a raw material for the production of soda ash by the ammonia soda method.
3. Used in inorganic and organic industry as raw material for production of caustic soda, chlorate, hypochlorite, bleaching powder, refrigerant in refrigeration system, raw material for organic synthesis and salting out. Used as a heat treatment agent in the steel industry. A high-temperature heat source is mixed with potassium chloride, barium chloride, etc. to form a salt bath, which can be used as a heating medium to maintain a temperature between 820 and 960°C. It is also used in glass, dyes, metallurgy and other industries.
4. Analytical reagents are used as fluorine and silicate trace analysis reagents.
5. Soda ash prepared by Hou’s caustic soda method: Step 2: Mix the ammonium bicarbonate solution prepared in step 1 with sodium chloride solution to obtain sodium bicarbonate and ammonium chloride at 10°C.

Food industry

• It is used for pickling in the food industry and fishery. Sodium chloride powder is used as a raw material for seasoning and refined salt.
• When salt is added to cooking, it can remove the peculiar smell of raw materials and enhance the taste, and this is the freshness effect of salt. “Light and tasteless, salty and tasteless” means that the amount of salt used must be moderate in order to achieve its unique function.

Medical treatment

Sodium Chloride Injection

Sodium chloride powder is very important to life on Earth. Most biological tissues contain many types of salts. The concentration of sodium ions in the blood is directly related to the regulation of safe levels of body fluids. The conductivity of nerve impulses due to signal transduction is regulated by sodium ions.

Water containing 0.9% sodium chloride has the same osmotic pressure as plasma, so it is called physiological saline. Saline is a major bodily fluid substitute, widely used for the treatment and prevention of dehydration, and is also used intravenously for the treatment and prevention of hypovolemic shock.

Unlike other primates, humans excrete large amounts of sodium chloride through sweat.

Sodium chloride powder is indispensable for people. The total amount of sodium ions contained in the body of an adult is about 60 g, of which 80% is present in the extracellular fluid, that is, plasma and intercellular fluid. Chloride ions are also mainly present in the extracellular fluid. The physiological functions of sodium ions and chloride ions are mainly as follows: 

1. Maintain the osmotic pressure of the extracellular fluid.
2. participates in regulating the body’s acid-base balance.
3. Chloride ions are involved in the production of gastric acid in the body, and sodium chloride powder also plays a role in maintaining normal excitability of nerves and muscles.

Agriculture

Its aqueous solution can be used for seed selection. NaCl solution is made up according to the needs of the species and its density is greater than that of water. When the seeds are placed in a Sodium chloride powder solution, they are full of sinking rather than floating.
