1313-84-4 - Application:

Sodium Sulfide Nonahydrate (CAS: 1313-84-4), odor of hydrogen sulfide; the color changes on exposure to light and air, first turning to yellow and then becoming brownish-black, deliquescent; density 1.43 g/cm3; decomposes at about 50℃; soluble in water; aqueous solution strongly alkaline; slightly soluble in alcohol; insoluble in ether. 

Sodium Sulfide Nonahydrate is used in making sulfur dyes; for dehairing of hides; removing sulfur from viscous rayon; engraving and lithography; cotton printing; manufacturing rubber; paper pulp; and as a photographic reagent. Other major applications are for treating paper and for extracting gold ores where oxidized metal ores are converted to sulfides prior to froth flotation. Sodium sulfide also is used in preparing many other sulfides and as an analytical reagent. Used in the manufacture of dyes, sulfides, and used as ore flotation agent, hide depilatory agent, paper cooking agent.
