Abstract: The thermal decomposition kinetics of solid Zinc(II) bis(dialkyldithiocarbamate) complexes, Zn (S2CNR2)2, where R= i-C3H7, n-C4H9, i-C4H9 and n-C5H11, were studied by using isothermal thermogravimetric heating technique. Results show that the thermal decomposition of these complexes occurs in a homogeneous liquid phase, after melting, according to a unidimensional phase-boundary reactions model, R1. The thermal stability was found to be in the following order: Zn(S2CNBui2)2< Zn(S2CNPri2)2< Zn(S2CNBun2)2< Zn(S2CNPen2)2.
