Charge transfer (CT) complexes were carried out using the most widely selling and effective pharmaceutical drugs as Pantoprazole (PANT) and Omeprazole (OMER) as electron donors; solid interaction with different benzoquinone derivatives as acceptors and  Iodine were isolated and characterized by IR and 1H-NMR (Nuclear magnetic resonance) .Thermo gravimetric analysis with different heating rates (TGA) were studied  on solid state complexes using computational integral methods for Coats Redfern and Ozawa using various solid state kinetic reaction models and established activation energy, energy band gape and thermodynamic parameters . The Differential Scanning Calorimetric (DSC) technique was used to study the nature decomposition of charge transfer complexes. The morphological structure were discussed and examined via Scanning Electron Microscopy (SEM).The molecular structures of Pentaprazole, DDQ, CHLC and I2& charge transfer complexes  in the ground state were made by using Gaussian 03  program package.

Keyword: thermal kinetic studies, pharmaceutical drugs, benzoquinone derivatives, Computational chemistry.
