  • Cupric Nitrate (2019/09/18)

    Cupric Nitrate

    Deep blue crystal Catalyzer Cupric nitrate
    Copper blue orthorhombic crystal. Deliquescence. Decomposition of oxygen release 170. Soluble in water and ethanol, almost insoluble in ethyl acetate. 0.2mol/L aqueous solution of pH was 4. Relative density 2.05. Melting point 114.5. Oxidizing, and charcoal, sulfur or other combustible material and friction heating blow.
    Chinese name Cupric nitrate Copper copper English nickname dinitrate chemical formula Cu (NO3) 2 molecular weight 187.56CAS accession 3251-23-8EINECS accession No. 221-838-5 the melting point of 115 DEG C boiling 170 degrees of water soluble Soluble density 2,32 g/cm3 appearance of dark blue crystal flash point 170 C control information of the product attributes of unregulated chemical reagents.
    1.The physicochemical properties of copper nitrate
    Chemical property
    Cu (NO3) 2 (H2O) 2.5 () 2.5, the center copper is surrounded by water molecules and nitric acid, and is coordinated by eight sides.
    For the decomposition of copper oxide, nitrogen dioxide and oxygen at 170 degrees C: 2Cu (NO3) 2 (s), 2CuO (s) + 4NO2 (g) + O2 (g)
    Through the thermal decomposition of copper nitrate and will produce the gas into the water to produce nitric acid. This method and the Ostwald process is similar to the last step.
    2Cu (NO3) 2 + 4NO2 + O2 + 2CuO
    3NO2 + 2HNO3 + NO + H2O
    Soaked veneer of copper nitrate in flame issued under the emerald green light, adding nitrate will produce orange green.
    Use of cupric nitrate
    Analysis of strontium nitrate. Aromatic organic silicon compound nitration agent. Organic reaction catalyst.
