WORKING PROCESS sulfur dye auxiliaries directly factory chemical formula manufacturer sodium hydrosulfide
Chemical equation: 2NaOH+H2S=NA2S+2H2O
NA2S+H2S=2NAHS
First Step: Use sodium hydroxide liquid absorb hydrogen sulfide generate sodium sulphide
Second Step: When sodium sulfide absorption saturation,continue to absorb hydrogen sulfide generate sodium hydrosulphide.
APPLICATION sulfur dye auxiliaries directly factory chemical formula manufacturer sodium hydrosulfide
Sodium Hydrosulfide is used as an accelerating agent for synthesizing organic matter and as an aid to color products by sulfuration.Sodium Hydrosulfide can be used as depilatory in tanning and leather, and also be used to treat waste water.Sodium Hydrosulfide is taken as desulphur agent in chemical fertilizer, as sulfide dye agent in synthetic fibre and manufacture of ammonium sulfide, ethyl sulphur alcohol as well as raw material and semi-products in thiourea production.Sodium Hydrosulfide is widely applied as floatation agent in copper ore and sulfide dye agent in synthetic fibre.
