High-Pressure-Synthesis of Carbonates. III. Synthesis of Carbonates of Divalent Metals by Decomposition of their Oxalates under High CO2 PressureThe carbonates MCO3 (M = Mn, Fe, Co, Ni, Zn, Cd) are prepared by decomposition of their oxalates under CO2 pressure up to 3500 bar. The synthesis of CuCO3 runs only in presence of an oxidizing agent. VCO3 · 0,5 H2O is prepared from VCO3 · 2H2O under CO2 pressure. CrCO3 mixed with Cr2O3 arises from Cr(CO)6 under CO2 pressure.
Notes:
Durch Zersetzung ihrer Oxalate unter CO2-Drücken bis 3500 bar werden die Carbonate MCO3 (M = Mn, Fe, Co, Ni, Zn, Cd) erhalten. CuCO3 entsteht nur in Gegenwart eines Oxidationsmittels. VCO3 · 0,5H2O entsteht aus VCO3 · 2H2O unter hohem CO2-Druck. CrCO3 bildet sich im Gemisch mit Cr2O3 aus Cr(co)6 unter CO2-Druck.
