Caustic Soda 98% Industrial Grade A pure product is a crystal that is clear and colorless

Sodium hydroxide (Sodium hydroxide), also known as caustic soda, caustic soda, is a kind of inorganic compounds, chemical formula NaOH, sodium hydroxide has strong alkaline, strong corrosive, can be used as acid neutralizer, masking agent, precipitating agent, precipitation masking agent, color agent, saponification agent, peeling agent, detergent, etc., very wide range of uses.
Pure sodium hydroxide is a white solid, readily soluble in water, and its aqueous solution is astringent and greasy. When sodium hydroxide is exposed to air, it tends to absorb water and gradually dissolves when the surface is wet. This phenomenon is called delixing. Its relative density is 2.130. Melting point 318.4℃. Boiling point 1390℃. There are two kinds of solid and liquid caustic soda on the market: pure solid caustic soda is white, block, flake, rod, granular, crisp; Pure liquid caustic soda is a colorless transparent liquid. Solid caustic soda has strong hygroscopicity. Easy to dissolve in water, dissolve heat, water solution is alkaline, there is a sense of slippiness; Soluble in ethanol and glycerol; Insoluble in acetone and ether. Highly corrosive, corrosive to fiber, skin, glass, ceramics and so on. Hydrogen is produced by reaction with aluminum and zinc, boron and silicon. Disproportionation reaction with chlorine, bromine, iodine and other halogens; Neutralize with acids to form salt and water.
For paper making, cellulose pulp production; It is used in the production of soap, synthetic detergent, synthetic fatty acid and the refining of animal and plant oils. Textile printing and dyeing industry used as cotton desizing agent, refining agent and mercerizing agent. Chemical industry for the production of borax, sodium cyanide, formic acid, oxalic acid, phenol and so on. The petroleum industry is used to refine petroleum products and in oil field drilling mud. It is also used in the surface treatment of alumina, zinc and copper, as well as in glass, enamel, tanning, medicine, dyes and pesticides. Food grade products used in the food industry as acid neutralizer, can be used as citrus, peach peeling agent, as well as decolorizing agent, deodorizing agent.
