Sodium thiocyanate CAS 540-72-7
Sodium thiocyanate is a colorless crystal containing 2 parts of crystal water. At 30.4 ℃, it loses its crystal water and becomes anhydrous sodium thiocyanate, which is soluble in water and ethanol. It is produced by azeotropic distillation of sodium cyanide and sulfur slurry in industry, and is one of the purification products of coke oven gas in coking plants. It is produced from the waste liquid of anthraquinone disulfonic acid method.

Sodium thiocyanate can be used as an analytical reagent, such as for the determination of niobium in steel and for the production of organic thiocyanates for silver, copper, and iron. Sodium thiocyanate can also be used as a solvent for drawing polyacrylonitrile fibers, a color film processing agent, some plant defoliants, and an airport road herbicide
