Abstract

A complex of Cu (II) with 1- (6-HydroxyNaphthalen-2-yl) Butane-1, 3-DIONE (HNBD) was synthesized and characterized by elemental analysis, IR, UV and DTA-TG-DTG techniques. IR spectra as well as UV-visible absorption measurements indicated that Cu (II) ion was coordinated to the HNBD ligand. The TG-DTA-DTG curves showed that thermal decomposition of the anhydrous complex was a two-stage process and the residue of decomposition was CuO. The decomposition mechanism and non-isothermal kinetic parameters of the complex were obtained from the analysis of TG-DTG data using three kinds of integral methods (Coat-Redfern equation, HM equation, MKN equation) and differential method (Achar equation). The results indicate that the kinetic equations with parameters describing the thermal decomposition reaction are da/dt=3.35´1038[0.5 (1-a)3] e-50250.2/T with E=417.78 kJ/mol, A=3.53´1038/s, DS=487.55 J/K.mol and n=3 for the first stage, da/dt=4.74´105 (1-a)2 e-11723.6/T with E=88.76 kJ/mol, A=4.74´105, DS=-144.59 J/K /mol and n=2 for the second stage.
