Nature: Colorless orthogonal crystal, deliquescence, instability, at around 350 ℃ melting into black liquid, dissolving in water or alcohol. The aqueous solution is strongly alkaline, and H2S is released violently in the case of acid. Industrial production of Sodium Hydrosulfide is usually the solution, orange or yellow, bitter taste, corrosive to human skin.
Usage: it is used as raw material for producing semi-finished products of ammonium sulfide, Sodium methyl mercaptide and pesticide ethyl mercaptan.
It is widely used in the mining industry for copper ore dressing.
Used in leather industry for the removal of raw fur and tanning.
Used in chemical industry for the removal of the monomer sulfur from the active carbon desulfurizer.
Used in the production of artificial fiber for sulfite dyeing, etc.
Package: solid: 25kg plastic woven bag. Liquid: in bulk, in barrels or tanks.
Note: in case of special needs of the buyer, the supplier and the buyer can carry out the work according to the technical specifications or packaging specifications in the agreement.
