Description

Sodium Hydrosulfide Molecular formula : NaHS Molecular weight : *6.*6 CAS NO :*********5 Hs NO.: *******0 Output/Mon:***0MT Predominance: the flakes(thickness:1mm*2mm) ,less impurity and higher content of NaHS, lower iron,. ITEM Content flake NaHS&#****2;% Min *0 Na2S&#****2;% Max 1.5 Na2SO3&#****2;% Max1 Fe&#****2;% PPM *0 Na2CO3&#****2;% Max 0.6 Insolubles In Water&#****2;% Max 0.**5 Appearance yellowish flake Synonyms: Sodium Hydrosulphide ,Sodium Hydrogen Sulphide, Sodium Hydrogen Sulfide, Sodium Sulfhydrate, Sodium Bisulphide. 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 ion , sodium sulfide, sodium carbonate, Insolubles mpurity in water. dip-dying in the leather production , it can disperse the fibre equably. less iron insure the appearance and good quality of leather. Producing Method: absorb sulfureted hydrogen(H2S) through subtractive ionic film. Properties: White needle system crystal, easily being deliquescent, soluble in water and alcohol, water solution with strong alkaline. Reacted with acids and liberates hydrogen sulfide. Industrial grade is generally in solution form with pale yellow color, slight rotten egg smell. Packing: *5kgs net in PP bag with PE liner, or **0kg bag , Storage: Keep only in closed, properly labeled containers. Do nor store in zinc, aluminum, or copper containers. Store in cool, dry, ventilated area to prevent it from being deliquescent. Separated from acids, acidic materials, oxidizing agents.
