        Sodium hydroxide

        Sodium hydroxide

        Molecular formula: HNaO
        Molecular weight: 39.99710
        CAS NO: 1310-73-2
        [Character] This reagent is white uniform granular or flake solid. Easily absorb moisture and carbon dioxide in the air, and easily dissolve in water.
        [To use] Granular caustic soda is mainly used as a chemical raw material and an important chemical basic raw material with a wide range of uses. In the chemical industry, it is used in the manufacture of formic acid, oxalic acid, borax, phenol, sodium cyanide, soap, synthetic fatty acid, synthetic detergent, etc. In the textile printing and dyeing industry, it is used as a solvent for cotton cloth desizing agent, scouring agent, mercerizing agent, vat dye and Haichang blue dye. Used in the smelting industry to manufacture aluminum hydroxide, aluminum oxide and metal surface treatment agents. In the instrument industry, it is used as an acid neutralizer, decolorizer, and deodorizer. The adhesive industry is used as starch gelatinizer and neutralizer. In addition, it is widely used in enamel, medicine, cosmetics, tanning, coatings, pesticides, glass and other industries.
        [Standard] The maximum content of impurity is calculated by %
