• Detailed Description:

  Cas No. :1313-82-2 Quality Standard: GB10500-89
  Molecular Weight:78.4
  Character of Na2S.XH2O: The non-
  water Na2S.XH2O is white crystal,
  and it is easy to be
  deliquescence. The relative
  density is 1.856 (14 centigrade),
  and its melting point is 1,180
  centigrade. It dissolves in water
  at 10 centigrade at which the
  solubility is 15.4g / 100ml
  water. When at 90 centigrade, the
  solubility is 57.2g/100ml water.
  It will react with acid, and
  become sulfureted hydrogen. It
  dissolves in water slightly, but
  not dissolves in aether. The
  watery liquid shows strong
  alkalescence, so it is also
  called sulfuration alkali. When
  it dissolves in sulfur, it
  produces the Na2S.XH2O. Because
  of impurity, its industrial
  product is pink, brown pink, and
  khaki. It has corrosive and
  toxicity. When under the air, it
  is easy to be oxygenated and
  become hyposulphite.
  Usage: In dye industry, it used
  to produce sulfuration dye; it is
  also the raw material of
  sulfuration green and sulfuration
  blue. In printing and dyeing
  industry, it serves as the dying
  helper in melting sulfuration
  dye. In leather industry, it used
  to hydrolyze in order to denude
  of peltry; it also can make the
  Na2S.XH2O and accelerate the dry
  peltry’ intenerating. In paper
  making industry, it serves as
  boiling helper in making paper.
  In weave industry, it used to
  doff saltpeter of man-made fibrin
  and to revert nitration goods. In
  medicine industry, it used to
  produce febrifuge. Besides that,
  it also can used to produce
  hyposulphite and excessive
  Na2S.XH2O
