Description
- General description: Ammonium oxalate monohydrate is a diammonium salt of oxalic acid. Its refined crystal structure has been investigated by three-dimensional diffraction studies.[1] Influence of bivalent [Mn(II), Co(II), Ni(II)] and trivalent cations [Fe(III), Cr(III)] impurities on the growth rates of ammonium oxalate monohydrate crystals has been described.[2] Its space group and unit cell parameters have been analyzed by neutron diffraction studies.[3] Its IR spectra have been compared with that of isolated coal-solubilizing agent (CSA).[4]
- Application: Ammonium oxalate monohydrate may be used in the preparation of tetramethylammonium oxalate.[5]
