Sodium Hydrosulfide

Description:

Sodium Hydrosulfide

Product: Sodium Hydrosulfide
MF: NaHS
Molecular Weight: 56.06
Appearance: yellow flakes
Application: Mainly used by mill run, pesticide, dye, waste water treatment, leather production and organic compound. It is the raw material to produce ammonium sulphate and ethanethiol ( semi-finished products ), and can be used in the copper ore beneficiation, also in the sulfurous acid dyeing of manmade fibres.
Property: Less impurity and higher content of NaHS, lower iron, Sodium Hydrosulfide is needle system crystal, easily being deliquescent, soluble in water and alcohol. Its water solution is strong alkaline. Sodium Hydrosulfide react with acids and liberates hydrogen sulfide. It becomes black liquid when the temperature is about 350°c. The industrial goods is solution, orange or yellow, bitter taste.

Physicals:

Sodium Hydrosulphide (thickness:1mm-2mm) ,less impurity and higher content of NaHS, lower iron,.Sodium Hydrosulphide is needle system crystal, easily being deliquescent, soluble in water and alcohol, water solution with strong alkaline. Sodium Hydrosulphide react with acids and liberates hydrogen sulfide. Industrial grade of Sodium Hydrosulphide is generally in solution form with pale yellow color, slight rotten egg smell. Available form: Flake form and solid fused form.

Application

Mining industry

Ÿas the activator for the sulfidization of oxide minerals. Florrea NaSH has a much lower alkalinity than Na2S. When in contact with oxygen (air),it lowly oxidizes. If a solution of NaSH is heated, it is converted into Na2S and H2S. It is a good replacement

for NsS.

Ÿas the flotation depressant for Cu and Fe sulfide minerals in Cu/Mo separation

Leather industry (tanning) as de-hairing agent

Pulp and paper industry, metal extraction from aqueous solutions,

Textiles (sulphur dye) and chemical processing

Storage:

Sodium Hydrosulphide is recommended to be kept only in closed, properly labeled containers. Do nor store in zinc, aluminum, or copper containers. Sodium Hydrosulphide is stored in cool, dry, ventilated area to prevent it from being deliquescent. Separated from acids, acidic materials, oxidizing agents.
