The chemical compound with the formula NaHS.

Sodium Hydrosulfide is applied in the leather industry, waste water treatment, soil remediation, the mining industry and pulp paper and amongst others.

 

Properties: Colorless needle-like crystal,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.

 

Use: Used in the synthesis of organic intermediates and in the preparation of auxiliary agent of sulfur dyes;in the waste water treatment;it is the raw material to produce ammonium sulphate and ethanethiol(semi-finished products);used in the copper ore beneficiation,also in the sulfurous acid dyeing of manmade fibres.

Working Process                                               

 

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.
