Sodium Sulphide (
Chemical name: Sodium Sulphide
Na2S.
Product NO.: *******0
CAS NO. : ********2
Molecular Ormula: Na2S Molecular
Weight: *8.*4 Standard: GB/T*********0.
Nature: yellow or red flakes, strong
moisture absorption, soluble in water, and water
solution is strongly alkaline reaction. Sodium sulphide
will cause burns when is touched with the skin and
hair. The method of solution in the air will slowly
oxygen.
Sodium thiosulfate, sodium sulfite, sodium sulphide and
sodium polysulfide, because sodium thiosulfates
generating speed is faster, its major product is sodium
thiosulfate. Sodium sulphide is deliquesced in the air
and carbonated so that it is metamorphic, and
constantly release hydrogen sulfide gas. The industrial
sodium sulphide includes impurities, so its color is
red. Specific gravity and boiling point are influenced
by impurities.
Function and Usage: sodium sulphide is
used to produce vulcanization dye, sulphur cyan,
sulphur blue, dye intermediates reductance, and other
nonferrous metallurgy industry used for ore flotation
agents. Sodium sulphide can also make the depilatory
cream in the leather industry. It is cooking agent in
the paper industry. Meanwhile, sodium sulphide is also
used to produce Sodium thiosulfate, sodium sulfite and
sodium polysulfide.
