Oct 13, 2017

Sodium hydroxide (NaOH) is extremely versatile. Used in the production of paper, soap, dyes, rayon, smelting metal, oil refining, cotton fabric finishing, the upgrading of coal tar products, as well as food processing, wood processing and machinery industry and so on.

Sodium hydroxide chemical experiment

Can be used as a chemical experiment. In addition to the use of reagents, because it has a strong water absorption and deliquescence, can also be used as alkaline desiccant. [6] can also absorb acid gases

Sodium hydroxide chemical industry

Sodium hydroxide is widely used in the national economy, and many industrial sectors require sodium hydroxide. The largest department of sodium hydroxide is the manufacture of chemicals, followed by paper making, aluminizing, refining, rayon, rayon and soap making. In addition, in the production of dyes, plastics, pharmaceuticals and organic intermediates, the regeneration of old rubber, metal sodium, water electrolysis and inorganic salt production, the preparation of borax, chromium salt, manganate, phosphate, etc., but also use A lot of caustic soda. At the same time sodium hydroxide is one of the important raw materials for the production of polycarbonate, superabsorbent polymer, zeolite, epoxy resin, sodium phosphate, sodium sulfite and sodium salt.
