The preparation and thermal stability studies of metal soaps of hura creptitans seed oil

J.A.Idiaghe, F.O.Aguele, Ekebafe

Oil extracted from Hura Crepitans seeds was used to prepare metal soaps of Zinc, Lead, manganese and Cobalt by chemical displacement method. The metal soaps obtained were subjected to thermal treatments at 443K, 453K and 463K. Thermal decomposition rate constants, activation energies and other thermodynamic data were obtained for eachmetal soap. Thermal stabilities of the soaps were found to decrease in the order: Co > Pb > Mn > Zn. The free energy and enthropy values of the soaps indicated that their decomposition processes are non-spontaneous.
