Applications & Uses

Applications

Sodium hydrosulfide is used as a reactive form of sulfur and acts as an intermediate in the production of other chemicals, including thio-chemicals used in textile processing, in the production of flame retardant resins, and in vulcanization accelerators. Sodium hydrosulfide is also used as a processing aid in the production of a variety of industrial products. It is a de-hairing agent in the production of fine leathers. In mining, it is a flotation agent, helpful in the precipitation of metals from ore slurries. Sodium hydrosulfide is also valuable as a raw material in the production of heat-resistant plastics for the auto and electronic industries. In paper making, Sodium hydrosulfide is used to add sulfidity to cooking liquor in kraft pulp mills.

Safety & Health

Safety Information

Sodium Hydrosulfide 39% is classified as a hazardous substance. Although hydrogen sulfide (H₂S) forms a stable bond with caustic in the NaSH solution, toxic vapor concentrations of H₂S above the liquid are possible and typical for high quality NaSH solutions. For this reason NaSH should always be handled in closed systems under inert gas while vapors should be treated before venting into the air. Tank containers should not be opened at any time unless the tank is properly decontaminated.

Storage & Handling

Storage Information

Store under nitrogen atmosphere in closed storage tanks. Requirements regarding storage tank design are available on request.
