Thermal Decomposition Kinetics of Dialkyldithiocarbamates by Using the Isothermal Thermogravimetry

M.C.D. Silva, M.M. Conceicao, J.C.O. Santos and A.G. Souza


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.
