Detailed Description
Molecular Formula ：Na2S
M.W.：78.04
Nature：Flake, HeGongSe, soluble in water, soluble in alcohol, ether, insoluble in water, the strong alkali in air is easy oxidation, toxic. The strong smell solution, because the method of S2 - the formation of hydrogen sulphide hydrolysis. Pure method for colorless crystalline powder. Hygroscopic, soluble in water. A strong alkali solution. Touching skin and hair caused burnable. Therefore LiuHuaJian known method. The method of solution in the air will slowly oxidation sulfur and sodium, as sodium, sodium and method. Because of the sulfur and sodium generated faster, so is the main product oxidation sulfur and sodium. The method in the air, and ChaoXie carbonization and metamorphism, constantly release hydrogen gas. Because of its industrial method containing impurities are pink color, palm red, yellow. Gravity, melting, boiling point, but also because of impurity influence. When exposed to the method of humid air, Na2S and its hydrate ejective hydrogen sulfide.
Uses：
Used in the manufacture of dyes, curing agent, leather, metal smelting photography, rayon denitration etc. Widely used in leather, paper, dressing, dye intermediates, printing and dyeing, organic produce, pharmaceutical, monosodium glutamate, man-made fibers and special engineering plastic, PPS, alkali rubber, is also used for making sodium sulfide method, sodium, etc., in the military industry also have certain USES.
Health hazards：
This product can decompose the h2s in gastrointestinal tract, oral after can cause h2s poisoning. For skin and eyes have corrosion, is harmful to the environment, this product has strong corrosive, inflammable, irritating, can cause human body burns
