Abstract

A number of 7 complexes of the [Co(DH)2(amine)2)]I type (DH2 stands for dimethyloxime) have been studied by means of thermogravimetry and differential scanning calorimetry in nitrogen atmosphere, by using heating rates of 2.5, 5 and 10 K min−1. In all cases an endothermal deamination reaction occurs leading to the relatively stable [Co(DH)2I(amine)] intermediate. For this reaction apparent kinetic parameters have been derived. The influence of heating rate is discussed. The validity of a linear and a non-linear kinetic compensation law was verified.
