Studies on Complexes of Transition Metals with Schiff Bases(Ⅱ)——Studies on the Non-Isothermal Kinetics of Thermal Decomposition of Complex of Nickel (Ⅱ) with N-Salicylideneglycine Tripyridine

Abstract

Abstract: The thermal decomposition of the complex of nickel (Ⅱ) with N-salicylideneglycine tripyridine and its kinetics were studied under the non-isothermal condition by TGand DTAtechniques.The non-isothermal kinetic data were analyzed by means of Achar method and Coats-Redfern method.The possible reaction mechanism was suggested by comparing the kinetic parameters.The results show that this thermal decomposition is a second-order chemical reaction.The kinetic equation can be expressed as:da/dt=Ae^-E/RT·(1-α).The mathematics expression of the kinetic compensation effect is found to be:lnA=0.2738 E+0.7774.

Key words: Schiff base, Nickel complex, Thermal decomposition, Non-isothermal kinetics
