Title

Kinetic study of thermal decomposition of metal dialkanoates

Download Paper

Abstract

The thermal solid phase-decomposition of zinc and cadmium dialkanoates (butanedioate and hexanedioate) was studied thermogravimetrically. Various kinetic parameters viz. Energy of activation, E, Entropy of activation, ΔS, Free energy of activation, ΔG, Enthalpy of activation, ΔH, and Frequency factor, Z have been calculated using Freeman-Carroll’s equation, Coats-Redfern’s equation integral method and Horowitz- Metzger’s equation approximation method. The trend of kinetic parameters was found to be different from that of thermal stability order. The low values of frequency factor, negative values of entropy of activation and positive values of free energy of activation and enthalpy of activation indicate slow nature of decomposition process and exothermic nature of system.

Key Words

Thermogravimetry, Metal dialkanoates, Frequency factor, Activation energy, Entropy of activation.
