Cuprous thiocyanate Chemical Properties,Uses,Production
Chemical Properties
Copper(I) thiocyanate, CuSCN, [1111-67-7], MW 121.62, is a white powder when pure, but often the material of commerce is yellow. It is soluble in ammonia solution, alkali thiocyanate solutions, and diethyl ether, but it is only slightly soluble in water and dilute mineral acids. It is stable in air in the absence of moisture, but it slowly decomposes in the presence of moisture in air. It is used as an antifouling pigment.
Characteristics
Copper thiocyanate (CuSCN) is also a wide bandgap (3.6?eV) semiconductor and has a work function of about ?5.3?eV. The conductivity ranges between 10-2 and 10-3 S?cm-1, good stability, shows good transparency throughout the visible and near infrared spectrum. It has good chemical stability. It can be deposited through a solution processing approach at low temperature, making it compatible with flexible substrates. By using copper thiocyanate (CuSCN) instead of P3HT as the HTL, a higher device PCE was achieved.
Uses
In marine antifouling paints; in primer compositions for explosives industry.
Preparation
Copper(I) thiocyanate is prepared by the reaction of alkali metal thiocyanates with copper(I) chloride at 8090°C or by the reaction of copper(II) sulfate solutions with alkali metal thiocyanate in the presence of sulfite. It can also be prepared by precipitation from copper(II) salt solutions with hydrogen thiocyanate.

Structure and conformation
At least two polymorphs of cuprous thiocyanate have been characterized by X-ray crystallography. They both feature copper(I) in a characteristic tetrahedral coordination geometry. The sulfur end of the SCN- ligand is triply bridging so that the coordination sphere for copper is CuS3N.
Incompatibilities
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides
Waste Disposal
Copper-containing soluble wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. If recovery is not feasible, the copper can be precipitated through the use of caustics and the sludge deposited in a chemical waste landfill. Copper-containing wastes can be concentrated to the point where copper can be electrolytically removed and reclaimed. If recovery is not feasible, the copper can be precipitated by alkali; the cyanide destroyed by alkaline oxidation yielding a sludge which can be sent to a chemical waste landfill. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office
