Abstract: | The decomposition of K2Co(C2O4)2] and K3Co(C2O4)3] has been studied using TG. In the case of the latter compound, the first step involves the rupture of all the oxalates and one of the resultant carbonates to liberate CO2 and three molecules of CO. Subsequent steps involve the loss of CO2. In the case of K2Co(C2O4)2], four decomposition reactions are observed. The first involves the loss of only CO. Subsequent steps involve loss of CO2, CO2 and CO, and CO2, respectively. Basic carbonates appear to be the intermediate products. Kinetic parameters are presented for most of the reactions. |
