Received trial consignment of sodium thiocyanate. Sodium thiocyanate (sodium thiocyanate) - colorless hygroscopic crystals with an orthorhombic lattice. It is readily soluble in water. At temperatures above 30.4 ° C sodium thiocyanate crystallizes from water in the anhydrous salt. At lower temperatures, as the dihydrate NaCNS * 2H2O. When heated above the melting point can be decomposed into sodium cyanide NaCN and sodium sulfide Na2S.
Sodium thiocyanate is used:
# as a reagent for dyeing and printing fabrics;
# as a reagent in photography;
# in analytical chemistry as a reagent for the photometric determination of the ions Fe, Co, Mo, W and others.
# for other thiocyanates;
# for the manufacture of spinning solutions in the manufacture of acrylic fibers;
# as a defoliant and desiccant for lupine.
