Industrial Grade NaHS Sodium Hydrosulfide with Cas No 16721-

2020-09-07 15:07

Sodium Hydrosulfide
 
Colorless needle-like crystals. Deliquescence. At the melting point, hydrogen sulfide is liberated. Easily soluble in water and alcohol. The aqueous solution is strongly alkaline. It reacts with acid to generate hydrogen sulfide. Bitter taste. Used in the dye industry to synthesize organic intermediates and to prepare auxiliaries for the preparation of sulfur dyes, in the leather industry for dehairing and tanning of hides, in the chemical fertilizer industry to remove monomer sulfur in activated carbon desulfurizers, and in the mining industry for copper ore. It is used for sulphurous acid dyeing in ore dressing and man-made fiber production. It is the raw material for the manufacture of semi-finished products of ammonium sulfide and pesticide ethyl mercaptan. It is also used for wastewater treatment.
