Detailed Description
Detail product description We are leading manufacturer and exporter of sodium hydrosulphide for tanning, textile, dye, chemical, water treatment and mining industry. MANUFACTURING PROCESS: NaHS is primarily produced bu scrubbing a H2S stream with NaOH, as shown in the following reaction: Hydrogen Sulfide + Sodium Hydroxide = Sodium Hydrosulfide + Water H2S NaOH NaHS H2O Synonyms: sodium hydrosulfide Molecular Formula: NaHS Molecular Weight: 56.06 CAS Number: 16721-80-5 H.S.CODE: 28301090 U.N NO: 2949 DANGEROUS CLASS: 8 Appearance: yellow flakes or solids Specifications: Content: 70%min Na2S: 3.5% max Fe: 30ppm Water Insoluble: 0.05%max Na2SO4: 0.2%max Applications: NaHS is a key component many industrial process involving sulfur requirements: 1.Specialty chemicals: NaHS is used in various industries for applications including, but not limited to agricultural, dyes, and other chemical processing. 2.Environmental applications NaHS is an effective tool in a waste treatment programs requiring stabilization and reduction of heavy and toxic metals through precipitation. 3.Mining: NaHS is an effective means of sullfidizing oxide ores and is used most commonly to separate Copper (Cu)from Molybdenum(Mo). NaHS does this by depressing the Cu from the Cu-Mo concentrate, allowing for conventional floatation metal separation. 4.Pulp and paper NaHS is used in the Kraft pulping process to prepare synthetic cooking liquor (white liquor) during pulp mill outages and as a make-up chemical to replace lost sulfur values. It may also be used as a scrubbing media for residual chlorine dioxide generated and consumed in mill bleach plants. 5.Tanning NaHS is used for removing hair from hides at the beginning of the tannery process Packing: 25kgs plastic woven bags, or 900kgs jumbo bags (Flakes) 150/320kg iron drums (solid)
