Product Description Basic InformationProduct Name: Sodium HydrosulfideOther Names:Sodium sulfohydrate; sodium hydrosulphide; Sodium Hydrogen Sulphide; Sodium Hydrogen Sulfide; Sodium Sulfhydrate; sodium bisulfideMolecular Formula: NaHSUN No.: 2949HS No.: 2830109000CAS No.: 16721-80-5EINECS No.: 240-778-0Hazard Class: 8Purity: 70%Appearance: Yellow FlakesGrade Standard: Industrial GradePhysical and Chemical PropertiesSodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half-neutralization of hydrogen sulfide (H2S) with sodium hydroxide. NaHS is a useful reagent for the synthesis of organic and inorganic sulfur compounds, sometimes as a solid reagent, more often as an aqueous solution. Solid NaHS is colorless, and typically smells like H2S owing to hydrolysis by atmospheric moisture. In contrast with sodium sulfide (Na2S), which is insoluble in organic solvents, NaHS, being a 1:1 electrolyte, is more soluble. Alternatively, in place of NaHS, H2S can be treated with an organic amine to generate an ammonium salt. Solutions of HS? are sensitive to oxygen, converting mainly to polysulfides, indicated by the appearance of yellow.Grade Standard: Industrial GradeITEMSTANDARD NaHS % min 70.0 Na2S% max 1.50 Na2SO3% max 1.00 Fe max 30 PPM Na2CO3 % max 0.60 Matter Insoluble in water % max 0.005PackagePackageQuantity (Without Pallet) 20'GPQuantity (With Pallet) 20'GP25kgs Bag22MT20MT900kgs bag18MT18MTApplication1.Its main uses are in cloth and paper manufacture as a makeup chemical for sulfur used in the kraft process2.as a flotation agent in copper mining where it is used to activate oxide mineral species3. in the leather industry for the removal of hair from hides.StorageStore in a cool, dry place.
