Sodium Hydroxide (Caustic soda, caustic soda) CAS 1310-73-2

Sodium hydroxide is one of the main chemical reagents used in various industries. It is used to neutralize acids, process food and textile products, produce paper, soap and other household products. Due to its high alkalinity, the substance requires strict compliance with safety measures.

Chemical structure and synthesis

Sodium hydroxide has a simple formula:

NaOH

The main method of its production is the electrolysis of a solution of sodium chloride (salt), known as the process of Chlorine–gap electrolysis, in which the separation of NaOH and chlorine occurs. The resulting product is characterized by high purity and stability.

Physico-chemical properties

Sodium hydroxide is white granules or flakes that are highly soluble in water with the release of a large amount of heat. It has a pronounced alkalinity, high corrosion activity and the ability to react instantly with acids and some organic compounds, which requires careful handling.

Application

Applies:

• In the chemical industry for the neutralization of acids and the synthesis of organic compounds.

• In the production of paper and textiles (for processing raw materials and removing impurities).

• In soap making and household chemicals for the production of cleaning products.

• For wastewater treatment and degreasing of metal surfaces in metallurgy.

Conclusion

Sodium hydroxide is an indispensable industrial reagent due to its high alkalinity and versatility of application. Its use requires strict compliance with safety regulations, which ensures efficient technological processes in various industries.
