Sodium thiocyanate is a white, inorganic compound that appears as orthorhombic crystals or a powder. It is readily soluble in polar solvents such as water, ethanol, and acetone; its aqueous solutions are neutral, and it is highly hygroscopic in air. As a key chemical raw material, sodium thiocyanate is primarily utilized as a spinning solvent for polyacrylonitrile fibers (acrylics), a reagent for chemical analysis, and a developer for color photographic film.

Function
Acrylic Fiber Production: Sodium thiocyanate serves as the most critical solvent in the production of polyacrylonitrile fibers (acrylic fibers). In the wet-spinning process, it acts as the primary component of the coagulation bath, exerting a decisive influence on the fiber’s formation, tensile strength, and overall quality.
Other Applications: It is utilized as a herbicide for airport runways and as a plant defoliant, helping to control weed growth or facilitate the shedding of leaves in crops.
Electroplating Industry: It is employed in black nickel plating processes to enhance the brightness and adhesion of the plated coating; it is also used in cyanide copper plating, cyanide silver plating, and processes for stripping nickel plating from copper or copper-tin alloy substrates.
Concrete Admixtures: Acting as an early-strength agent or water-reducing agent for concrete, it accelerates the hardening process and boosts early compressive strength.
Chemical Raw Materials: It is used in the synthesis of artificial mustard oil, sulfonamide drugs, Vitamin B1, and other pharmaceutical intermediates, as well as intermediates for agricultural herbicides and insecticides; it also serves as an additive in rubber processing.
