[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods, chlorine salt is salty

Chlorine salt properties

Chloride salts are salt compounds containing chloride anions, which usually appear as white or pale yellow crystalline solids. Common chlorine salts include sodium chloride (NaCl), calcium chloride (CaCl₂), and magnesium chloride (MgCl₂). These chloride salts have high solubility and good conductivity, and when dissolved in water, they can ionize to produce chloride ions (Cl), thereby affecting the conductivity of aqueous solutions. Chloride salts are mostly hygroscopic, especially calcium chloride and magnesium chloride, which easily absorb moisture in the air to form a solution.

Chlorine salt use

Chlorine salt is widely used in all walks of life. Sodium chloride is the most common table salt and is widely used for food flavoring and preservation. In industry, sodium chloride is an important raw material for the production of chlorine, caustic soda and other basic chemical products. Calcium chloride is commonly used in deicing and snow-melting agents, desiccants, and cement additives to enhance its frost resistance. Magnesium chloride is used in industry for the production of fireproof materials, refractory bricks and the extraction of magnesium metal. Chloride salt also has important uses in medicine, agriculture and environmental protection. For example, potassium chloride can be used for potassium fertilizer, and sodium chloride solution is used for medical rehydration.

Chlorine salt upstream and downstream raw materials

The production of chlorine salts involves a variety of upstream and downstream feedstocks. Taking sodium chloride as an example, its main raw material is sea water or salt ore, which is obtained by evaporation crystallization method. Calcium chloride and magnesium chloride are usually prepared from calcium ore and magnesium ore by reaction. For example, calcium chloride can be produced by reacting limestone with hydrochloric acid, and magnesium chloride can be produced by reacting brine with hydrochloric acid. Upstream raw materials mainly include various minerals and acids, while downstream products cover a wide range of chemicals, food, pharmaceuticals and agricultural products.

Chlorine salt storage method

Due to the strong hygroscopicity of chloride salt, special attention should be paid to moisture-proof during storage. Generally, chlorine salt should be stored in a dry, well-ventilated warehouse to avoid contact with moisture in the air. For calcium chloride and magnesium chloride with strong hygroscopicity, sealed containers shall be used for storage, or desiccant shall be placed in the warehouse. Prevent contact of chloride salts with acids to avoid chemical reactions. Chlorine salt storage should also be careful to stay away from fire, because some chlorine salts may decompose at high temperatures to produce toxic gases.

Chlorine salt market demand and trend

The market demand for chlorine salts is stable and growing, mainly due to its wide application in industry, agriculture and daily life. With the acceleration of industrialization and urbanization, the demand for industrial chlorine salts such as sodium chloride and calcium chloride is increasing year by year. The enhancement of environmental awareness promotes the application of chlorine salt in wastewater treatment, soil improvement and other fields. It is expected that the chlorine salt market will continue to expand in the next few years as technological advances and new application areas are developed.

Environmental and safety issues

There are some environmental and safety problems in the production, storage and use of chlorine salt. Heavy use of sodium chloride may lead to soil salinization and affect the growth of crops. Hygroscopic chlorine salts such as calcium chloride and magnesium chloride, if not handled properly, will cause water pollution. Chlorine salts may decompose at high temperatures to produce chlorine gas, which is toxic. Therefore, in the production and use of chlorine salt, it is necessary to take effective environmental protection and safety measures, such as improving the production process, strengthening wastewater treatment, and standardizing storage conditions.

Future development direction

In the future, the research and development of chlorine salt will develop in the direction of green environmental protection and efficient utilization. The development of new chlorine salt composite materials will enhance its application value in high-tech fields such as construction and electronics. Developing more environmentally friendly production processes, reducing waste emissions in the chlorine salt production process, and improving resource utilization will be an important development direction of the chlorine salt industry. Through technological innovation and management optimization, the sustainable development of chlorine salt in various industries will make positive contributions to the upgrading of the chemical industry and the progress of society.

Conclusion

As an important chemical raw material, chlorine salt has a variety of physical and chemical properties and a wide range of applications. Its production and use involves many upstream and downstream industrial chains, and the market demand is growing steadily. Chloride salts have certain environmental and safety challenges that need to be addressed through technological innovation and management improvements. In the future, with the in-depth promotion of the concept of green chemical industry, chlorine salt will usher in a broader development prospects, providing a solid foundation for the development of modern chemical industry.
