Oil occurred natural sources are considered to be the essential category of renewable sources and can be produced as of natural plants such as groundnut, they comprise generally of triglycerides. The main object of this work gives an outline of innovative result in the area of thermo gravimetric analysis for Copper (II) groundnut soap complexes. Solid state kinetics has fascinated the awareness of precise society not only due to its abundant applications in environment, energy, waste water treatment, pollution control and green chemistry but also due to their extensive variety of biological activities. TGA method has been useful to Copper (II) groundnut soap complex used for its thermal study and estimation of activation energy and pre-exponential factor. Thermodynamic parameters such as heat of dissociation ΔH, free energy change ΔG and entropy change ΔS have been estimated for the different steps of degradation with the fundamental method of Coats-Redfern, Broido, Horowitz-Metzger and Piloyan-Novikova method. The outcome of thermo gravimetric analysis expose that Copper (II) groundnut soap complex experience stepwise thermal degradation of ligand, saturated, mono- and polyunsaturated fatty acid segments of edible oils. It has been experiential to facilitate used for every equations applied, the stepwise energy of activation follow the array – Step III > Step II > Step I.
