Product Name：sodium hydroxide, caustic soda, causticflake

Molecular Formula: NaOH

CAS Number: 1310-73-2

EINECS Number: 215-185-5

Overview:It is a highly corrosive strong alkali, usually in the form of white flakes or granules, which can be mixed 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.

Uses: 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 due to its strong hygroscopicity. Caustic soda is widely used in the national economy and is required by many industrial sectors. The sector that uses the most caustic soda is the manufacture of chemical drugs, followed by chemical papermaking, aluminum smelting, tungsten smelting, rayon, artificial cotton and soap manufacturing. In addition, a large amount of caustic soda is also used in the production of dyes, plastics, pharmaceuticals and organic intermediates, the recycling of old rubber, the production of metallic sodium, the electrolysis of water, and the production of inorganic salts, the production of borax, chromium salts, manganates, phosphates, etc.
