Properties：Yellowish flake 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. The industrial good is solution, orange or yellow, bitter taste.

Alias: Sodium Hydrosulphide ,Sodium Hydrogen Sulphide, Sodium Hydrogen Sulfide, Sodium Sulfhydrate, Sodium Bisulphide.

Detailed Product Description

Predominance:mainly used by mill run, pesticide, dye ,leather production and organic compound. compared with other company, high purity,less impurity, not easy to be intenerated, especially less iron, sodium sulfide, sodium carbonate,Insolubles impurity in water. dip-dying in the leather production, it can disperse the fibre equably.less iron insure the   appearance and   good quality of leather.
