Product Detail

Properties

Sodium Hydroxide Solution

Product nature:

Pure product is colorless and transparent liquid. The relative density is 1.328-1.349, the melting point is 318.4 ℃, and the boiling point is 1390 ℃. Pure liquid caustic soda is called liquid alkali, which is a colorless and transparent liquid. Industrial products mostly contain impurities, mainly sodium chloride and sodium carbonate, and sometimes a small amount of iron oxide. When dissolved into concentrated alkali, most impurities will float on the liquid surface and can be separated and removed.

Essential information

Chemical name: sodium hydroxide

Molecular formula: NaOH

Molecular weight: 40.00

Properties

It is used to make special soap, insecticide, hard water softening, beet sugar refining, boiler descaling, glass lubrication, etc. it is also used to prepare organic synthesis and barium salt; 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. The sectors that use caustic soda most are chemical manufacturing, followed by papermaking, aluminum smelting, tungsten smelting, rayon, artificial cotton and soap manufacturing. In addition, in the production of dyes, plastics, chemicals and organic intermediates, the regeneration of old rubber, the electrolysis of metal sodium and water, and the production of inorganic salts, a large amount of caustic soda is also used in the production of borax, chromate, manganate, phosphate, etc.
