Neodymium Oxalate Hydrate Nd2(C2O4)3 nH2O CAS 14551-74-7 For Chemical Reagents

Neodymium oxalate, with the formula Nd2(C2O4)3·10H2O, is a chemical that is insoluble in water, usually in the form of rose-colored crystals. It is slightly soluble in water, resulting in a solubility of only 0.074g/100mL at 25℃. Neodymium oxalate has unique application value in the field of chemistry, especially in magnet manufacturing and glass manufacturing industries play an important role.
In recent years, with the progress of science and technology, the extraction technology of neodymium oxalate has also been innovated. For example, Shimane University in Japan has developed a new technology to extract high-purity neodymium oxalate from waste magnets at normal temperature and pressure, which not only improves the recovery efficiency, but also greatly reduces the cost, and is of great significance for the recycling of rare earth resources.

    Name: Neodymium oxalate hydrate
    Molecular formula: Nd2(C2O4)3·nH2O
    CAS: 14551-74-7
    Molecular weight: 732.69

    Description

    Neodymium oxalate is monoclinic. Insoluble in water. The neodymium oxalate can be precipitated from aqueous solution when it is dissolved in water at 25 ℃ for only 0.49 × 10-4mg / L. Neodymium oxide is dissolved in dilute nitric acid by heating reaction, and then added to methyl oxalate aqueous solution. After fully mixing, reflux for 3h, oxalate precipitates. Put it overnight at room temperature and filter it, wash it with water, ethanol and ether in turn to form neodymium oxalate hydrate.
