Kinetic Parameters from Thermogravimetric Curves of Manesium Soaps

Abstract

Thermogravimetric equations have been applied to evaluate Kinetic parameters of magnesium soaps (C₈, C₁₀ and C₁₂). Coats and Redfern derived equation for the thermal decomposition—shows first order kinetics. The activation energies have been determined from Horowitz-Metzger and Coats-Redfern equations. The data obtained from linear regression are in close agreement and are in the range (2 to 6 K Cal mol^–1). The parflmeters are found to be independent of the chain length of the anion of n-alkanoates.
