Sodium hydroxide Purity ≥ 98.0% CAS NO 1310-73-2
Description
Sodium hydroxide, solid dissolves in water and releases heat; also known as caustic soda, fire soda, and caustic soda, it is a common and important alkali.
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.
