Abstract

FARIAS, Robson Fernandes de et al. Kinetical study by TGA and DSC data of the thermal decomposition of some cadmium halide adducts. Quím. Nova [online]. 1998, vol.21, n.2, pp.164-166. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40421998000200011.

By DSC data, the kinetical parameters Ea , n and A were calculated for the thermal decomposition of the adducts CdCl2.2dmf, CdCl2.dmf and CdBr2.dmf (dmf= dimethylformamide) by using Rogers and Smith method. The found values were : Ea = 85, 176 and 101 kJ mol-1 , n= 0.23, 0.25, and 0.17, A= 2.40x109, 1.89x1019 and 1.07x109 respectively. By TGA data, the kinetical patameters for the thermal decomposition of the adduct CdCl2.1,5 dmeu (dmeu=dimethylethyleneurea) were calculated by using five different methods.

Keywords : thermal decomposition; kinetical parameters; cadmium adducts.
