Liquid alkali is a type of sodium hydroxide, which is liquid sodium hydroxide. Pure liquid caustic soda is called liquid alkali and is a colorless and transparent liquid.
The chemical name is sodium hydroxide, with the molecular formula NAOH, also known as caustic soda, caustic soda, or caustic soda.
The pure product is a colorless transparent liquid. Relative density 1.328-1.349, melting point 318.4 ℃, boiling point 1390 ℃. Pure liquid caustic soda is called liquid alkali, which is a colorless and transparent liquid. Industrial products often contain impurities, mainly sodium chloride and sodium carbonate, and sometimes a small amount of iron oxide. When dissolved into a concentrated alkali solution, most impurities will rise to the surface and can be separated and removed.
It is an important chemical basic raw material with a wide range of uses. The chemical industry is used to manufacture formic acid, oxalic acid, borax, phenol, sodium cyanide and soap, synthetic fatty acids, synthetic detergents, etc. The textile printing and dyeing industry is used as a solvent for cotton fabric desizing agent, scouring agent, mercerizing agent, vat dye, and blue dye. Manufacturing aluminum hydroxide, aluminum oxide, and metal surface treatment agents for the smelting industry. The instrument industry is used as an acid neutralizer, decolorizer, and deodorizer. The adhesive industry is used as a starch gelatinizer and neutralizer. In addition, it is widely used in industries such as enamel, medicine, cosmetics, leather making, coatings, pesticides, and glass.
Liquid alkali is transported by tank trucks or storage tanks. Caustic soda has extremely strong corrosiveness. When touched by the skin, it should be immediately rinsed with water. If splashed into the eyes, it should be rinsed with water or physiological saline for 15 minutes. In severe cases, seek medical treatment.
