Sodium Hydrosulfide/Sodium Hydrogen Sulfide-Flakes/NaHS/ Sodium hydrofide 70%flakes
Appearance: Brownish yellow flakes, easy to be deliquesced, it will decomposed and release hydrogen disulfide at its melting point, soluble in water and alcohols, its water solution is strongly alkaline, it will generate hydrogen disulfide when reacting with acids.
Application: Used in organic synthetic and preparation of sulfur intermediates and auxiliaries in dyes industry. Not only being used in hair removal and tanning in leather industry, but also in wastewater treatment. For the chemical fertilizer industry, it can take off the sulfur which is one of compositions for monomer desulfurizer of the activated carbon, and also are the raw material for manufacturing the Ethanethiol and semi-finished ammonium sulphide. A large number of In mining industry, a large number of NaHS are used for copper benefication . Staining for sulfite in Man-made fibers industry also is one of NaHS purposes.
