Resumo

CADMIUM HALIDE ADDUCTS.By DSC data, the kinetical parameters E a , n and A were calculated for the thermal decomposition of the adducts CdCl 2 .2dmf,CdCl 2 .dmfand CdBr 2 .dmf(dmf= dimethylformamide) by using Rogers and Smith method.The found values were : E a = 85, 176 and 101 kJ mol -1 , n= 0.23, 0.25, and 0.17, A= 2.40x10 9 , 1.89x10 19 and 1.07x10 9 respectively.By TGA data, the kinetical patameters for the thermal decomposition of the adduct CdCl 2 .1,5dmeu (dmeu=dimethylethyleneurea) were calculated by using five different methods.
