Products Description of Sodium hydroxide CAS#1310-73-2

Sodium hydroxide, also known as caustic soda and caustic soda, has the chemical formula NaOH. It is a highly corrosive strong alkali, usually in the form of white flakes or granules. It can be miscible with water to form an alkaline solution, and can also be dissolved in methanol. and ethanol. This alkaline substance is deliquescent and will absorb water vapor in the air as well as acidic gases such as carbon dioxide. Sodium hydroxide is one of the commonly used chemicals. It is widely used and is a necessity for many industrial processes: it is often used in the manufacture of wood pulp paper, textiles, soap and other cleaning agents, etc. It is also used in household alkaline drains.

Product Application of Sodium hydroxide CAS#1310-73-2

Sodium hydroxide has a wide range of uses. In chemical experiments, in addition to being used as a reagent, it can also be used as an alkaline desiccant because of its strong hygroscopicity. Caustic soda is widely used in the national economy, and many industrial sectors require caustic soda. The sector that uses the most caustic soda is the manufacturing of chemicals, followed by paper making, aluminum smelting, tungsten smelting, rayon, rayon and soap manufacturing. In addition, it is also used in the production of dyes, plastics, pharmaceuticals and organic intermediates, the regeneration of old rubber, the electrolysis of metal sodium and water, and the production of inorganic salts to prepare borax, chromium salts, manganates, phosphates, etc. A lot of caustic soda. Industrial sodium hydroxide should comply with national standard GB209-2006;

Industrial ion exchange membrane sodium hydroxide should comply with national standard GB/T11199-89;

Sodium hydroxide for chemical fiber should comply with national standard GB11212-89;

Edible sodium hydroxide should comply with national standard GB5175-85.

In industry, sodium hydroxide is usually called caustic soda, or caustic soda and caustic soda. This is because concentrated sodium hydroxide solution splashed on the skin will corrode the epidermis and cause burns. It has a dissolving effect on proteins and is highly irritating and corrosive (due to its dissolving effect on proteins, alkali burns are less likely to heal than acid burns). Instilling 0.02% solution into rabbit eyes can cause corneal epithelial damage. Mouse intraperitoneal LD50: 40mg/kg, rabbit oral LDLo: 500mg/kg. Dust irritates the eyes and respiratory tract and corrodes the nasal septum; when splashed on the skin, especially the mucous membrane, it can produce soft scabs and can penetrate into deep tissues, leaving scars after burns;
