The thermal decomposition of copper(II) oxalate has been studied under vacuum using a constant-volum apparatus and a microbalance; and under dynamic atmospheres of air, nitrogen and oxygen using thermogravimetry and differential scanning calorimetry.The decomposition was found to proceed to copper metal under an inert atmosphere and vacuum; while in air and oxygen, copper(II) oxide was found to be the decomposition product.In each case the decomposition was found to be exothermic with an enthalpy change of -9 +/- 2 kJ mol^-1 in nitrogen and -134 +/- 5 kJ mol^-1 in air.Isothermal kinetic analysis showed the data to fit an Avrami-Erofeev relationship with n=3 in each case.Arrhenius parameters are reported for each decomposition atmosphere and are compared to those of other transition-metal oxalates which appear in the literature.The presence of a preparation effect is noted, as seen with other oxysalts; however, no evidence for the formation of copper(I) oxalate has been found which has previously been speculated to be an intermediate in the decomposition.
