Sodium hydroxide is white flake solid, easily absorb moisture, belong to alkali class corrosive substance. Mainly used in metallurgy, petroleum, chemical industry, textile, papermaking, printing, dyeing, pharmacy, soap, sewage treatment and other industries. Have strong corrosive, water absorbability, can be used as desiccant, however, cannot dry so2, no2 and hydrogen carbon dioxide,etc. acidic gas. And can easily deliquesce in the air (the phenomenon belongs to a physical change); Soluble in water, and give off a lot heat at the same time .The melting point is 318.4 ℃. Except solubling in water , sodium hydroxide also can soluble in ethanol and glycerin, But insoluble in ether, acetone, liquid ammonia.
The liquid is a colorless, have astringency and satiny feeling. Sodium hydroxide will become metamorphic when react with carbon dioxide in air !
Using:
Sodium hydroxide is in one of main basic chemical raw materials the national economy, widely used in light industry, chemical industry, metallurgy, textile, medicine, pesticide, and other departments, and as the raw material the synthesis of organic chemicals and inorganic chemical products.
