Cuprous thiocyanate химические свойства, назначение, производство
Химические свойства
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.Использование
In marine antifouling paints; in primer compositions for explosives industry.Подготовка
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.Общее описание

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.Несовместимости
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, epoxidesУтилизация отходов
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 officeCuprous thiocyanate запасные части и сырье
