Description and Uses
Ammonium thiocyanate is a colorless solid which absorbs moisture and becomes liquid. Molecularweight= 76.12; Boiling point= 115℃; Freezing/Meltingpoint=160℃, decomposes at 170℃; Heat of solution=3.1 3 105 J/kg. Hazard Identification (based on NFPA-704 M Rating System): Health 2, Flammability 1,Reactivity 1, Corrosive. Soluble in water.
Colorless deliquescent crystals made by boiling an aqueous solution of ammonium cyanide with sulfur or polysulfides. It must be kept in a well-sealed container. The principal use for ammonium thiocyanate was in gold-toning formulas, but it was also used in a 5 percent solution to dissolve gelatin in overexposed carbon prints.
