Product Application of Sodium thiocyanate CAS#540-72-7

Sodium thiocyanate is a valuable chemical raw material and has important uses in various sectors of the national economy. Sodium thiocyanate is mainly used as a solvent for spinning acrylic fibers, chemical analysis reagents, color film film rinses, certain plant defoliants, and airport road herbicides. Sodium thiocyanate is also used in pharmaceuticals, printing and dyeing, rubber processing, black nickel plating, and artificial mustard. Oil, etc. The main industrial production processes are: separation of sodium thiocyanate from waste liquid in coke oven gas, synthesis of sodium thiocyanate with sodium cyanide and sulfur, and production of sodium thiocyanate by metathesis reaction of ammonium thiocyanate and sodium hydroxide. The synthesis of sodium thiocyanate requires high purity HCN as raw material, which is costly and harsh.
