Name

Sodium Sulphide  

Product NO.: 28301010

CAS NO. : 1313-82-2

Molecular Ormula: Na₂S Molecular Weight: 78.04   Standard: GB/T10500-2000.

Nature: yellow or red flakes, strong moisture absorption,   soluble in water, and water solution is strongly alkaline reaction. Sodium   sulphide will cause burns when is touched with the skin and hair. The method   of solution in the air will slowly oxygen.

Sodium thiosulfate, sodium sulfite, sodium sulphide and   sodium polysulfide, because sodium thiosulfate’s generating speed is faster,   its major product is sodium thiosulfate. Sodium sulphide is deliquesced in   the air and carbonated so that it is metamorphic, and constantly release   hydrogen sulfide gas. The industrial sodium sulphide includes impurities, so   its color is red. Specific gravity and boiling point are influenced by   impurities.

Function and Usage: sodium sulphide is used to produce   vulcanization dye, sulphur cyan, sulphur blue, dye intermediates reductance,   and other nonferrous metallurgy industry used for ore flotation agents.   Sodium sulphide can also make the depilatory cream in the leather industry.   It is cooking agent in the paper industry. Meanwhile, sodium sulphide is also   used to produce Sodium thiosulfate, sodium sulfite and sodium polysulfide.
