sodium sulfide

【Common Name】:Sodium sulfide; smelly base; sulfide ore; a sodium sulfide; nine hydrated sodium sulfide 【English name】:sodium sulfide CAS 1313-82-2 【Specification】:Industrial grade level ≥ 60% 【Chemical Formula】:Na2S 【Molecular formula】:78.04 【Appearance】: 1, colorless or light yellow crystalline particles, and industrial products for the massive red-brown or brick red.

Flake, brown red, soluble in water, slightly soluble in alcohol, insoluble in ether, the aqueous solution is strongly alkaline, easily oxidized in air, toxic. 2, strong moisture absorption, soluble in water. Water solution is strongly alkaline reaction. Touched the skin and hair will cause burns. Therefore, commonly known as sodium sulfide, sodium sulfide.

Aqueous solution of sodium sulfide in the air will be slowly oxidized to sodium thiosulfate, sodium sulfite, sodium sulfate and sodium polysulfide. 3, due to the formation of sodium thiosulfate faster, so the main product of oxidation is sodium thiosulfate.

Deliquescent sodium sulfide in the air, and carbonation and deterioration, and continuously released hydrogen sulfide gas. 4, industrial sodium sulfide containing impurities because of their color was pink, brown, khaki.

Weight, melting point, boiling point, but also because of the effects of different impurities. 【Effectiveness of the role】: 1 commonly known as sodium sulfide, water is so pure crystal white crystal axis.

Corrosive, easy deliquescence; soluble in water, the solution is alkaline; case of acid from the decomposition of hydrogen sulfide; easily oxidized in the air.

2 industrial products with different crystal water (Na2S • xH2O), typically containing about 60% sodium sulfide, sodium sulfide is mainly used for hair removal agent hides, pulp cooking agent, sulfur raw materials, dyes intermediates, reducing agent, textile dyeing mordant , ore flotation agent, also used as desulfurization agent and the production of viscose fiber sodium hydrosulfide and polysulfide raw materials. 【Packing method】:0.5 mm thick steel drums loaded in the strict closure, barrel, net weight not exceeding 100 kg.

Thread mouth bottle, Lid pressure bottles, plastic bottles or metal (cans) outside the ordinary wooden box.
