Abstract

Meera Sharma*, Ramakant and Vidhya Sagar

Thermogravimetric analysis have been used to evaluate kinetic parameters of cerium and thorium Soaps. The thermal decomposition of cerium and thorium soaps is kinetically of zero order and the energy of activation for the decomposition process lies in the range of 4-23 K. calmol-1. Infrared spectra indicate that the fatty acids with dimeric structure through hydrogen bonding between the carboxyl groups of acid molecules whereas the metal soaps have an ionic character.
