Synthesis and Studies on the Non-Isothermal Kinetics of Thermal Decomposition of La(NCS)3·3TMSO2

Abstract

Abstract: The complex of lanthanum isothiocynate with sulfolane was synthesized. The kinetics of thermal decomposition of the complex was studied under non-isothermal condition. The non-isothermal kinetic data were analyzed by means of the Achar method and the Coats-Redfern method. The possible reaction mechanism was suggested by comparison of the kinetic parameteres. The results show that this thermal decomposition is a second order reaction. The kinetic equation may be expressed as :da/dt = Ae_E/RT · (1 - a)_2.Mathematical expression of the kinetic compensation effect is found to be:InA = 0.218E - 0.637.

Key words: Lanthanum Jsothiocyanate, SulfoJane, Thermal decomposition, Non-isothermal kinetics
