Kinetics of the thermal decomposition of bis(dialkyldithiocarbamate) of palladium(II) complexes in isothermal and nonisothermal conditions

Dialkyldithiocarbamate of palladium(II) complexes, Pd(S2CNR2)(2). with R=C2 H5, n-C3H7. n-C4H9, i-C4H9 and C5H11 were synthesized from the direct react ion of PdCl2 with corresponding amine and carbon disulphide. The complexes were characterized by the techniques of melting points, infrared absorption spectroscopy and mass spectrometry. The thermal decomposition reaction of complexes have been studied by isothe rmal and nonisothermal thermogravimetry. Superimposed curves of TG/DTG/DSC show that these reactions occur in the liquid phase. The kinetic isothermal model that best adjusted the experiment data were the R1 model.
