Desiccant Basic Copper Carbonate | Basic Cupric Carbonate | Copper II Carbonate | Copper Green | 12069-69-1

Short Description:

Copper carbonate basic, also known as patina and copper green, with the chemical formula CuCO3·Cu(OH)2·XH2O, is a substance produced by the reaction of copper with oxygen, carbon dioxide, and water vapor and other substances in the air. When heated in air, it decomposes into copper oxide, water and carbon dioxide, dissolves in acids and produces the corresponding copper salts.

    Properties_.png

    Green powder, density 3.85, melting point 200°C decomposition, insoluble in cold water and alcohol, soluble in acid and form corresponding copper salt, soluble in aqueous solution of cyanide, sodium hydroxide, ammonium salt and alkali carbonate to form copper complexes. When boiled in an alkali metal carbonate solution, brown copper oxide is formed, which decomposes into black copper oxide at 200°C. It is unstable in hydrogen sulfide atmosphere. Basic copper carbonate has more than a dozen forms of compounds according to the ratio of CuO : CO2 : H2O. In industrial production, its molecular formula is CuCO3 Cu(OH)2 XH2O. The solubility in water is 0.0008%, and its decomposition temperature is 200-220°C with low toxicity.


    Desiccant basic copper carbonate is used in the inorganic salt industry to prepare various copper compounds for wood preservation and other fields.

    Packaging:25KG/Compound paper bag by three layer kraft paper lined with one layer of aluminized paper.
