PropertyColorless 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.
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, sodium sulfide, sodium
carbonate,Insolubles impurity in water. dip-dying in the leather
production, it can disperse the fibre equably.less iron insure
the appearance and good quality of leather.
UseUsed 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.
Packing Woven bag lined with plastic bag(net weight is *5 kg or **0kg bag , or 1oookg bag with pallet.or without pallet); or iron drum or plastic drum(net weight is **0kg)
