Characteristic:White rhombic
crystal of powder.The melting
point is approximately 287℃.It
is easily dissolved in the
water,alcohol and acetone.The
aqueous solution shows
neutrality.It can produces blood-
red ferric thiocyanate with
molysite and does not react with
ferrite.It produces yellow sodium
thiocyanate with concentrated
sulfuric acid and blue-black
cobalt thiocyanate with cobalt
salt .It produces mercuric silver
salt nantokite.It is easily
deliquesced in the air so it
should be sealed for storage.
