product description
Product Description of Sodium Hydrosulfide CAS#16721-80-5
Sodium Hydrosulfide is a sulfide compound. In pure form, it presents as colorless crystals. Industrial-grade products are usually light gray or pale yellow lumps, granules or powders due to trace impurities. It is hygroscopic and emits a typical hydrogen sulfide odor.
When dissolved in water, it forms a strongly alkaline solution and readily reacts with acids to release hydrogen sulfide gas. Correct handling and proper storage are essential to ensure safe industrial application.
Product Application of Sodium Hydrosulfide CAS#16721-80-5
Sodium Hydrosulfide is widely used in paper pulping, dye production, and desulfurization of rayon and cellophane fibers. In textile, paper, pulp and dyestuff industries, it acts as a bleaching and reducing agent to improve product quality.
In the leather industry, it is used for hide unhairing in tanning processes. In mineral processing, it serves as a flotation reagent for copper ore beneficiation. It is also an important intermediate in organic synthesis and a key raw material for manufacturing ammonium sulfate and ethanethiol.
