Studies on the synthesis and non-isothermal kinetics of thermal decomposition for the complex [Ba(dibenzo-24-crown-8)(H 2O) 2][Co(NCS) 4

Abstract

Crystals of the complex [Ba(dibenzo-24-crown-8)(H 2O) 2][Co(NCS) 4] were obtained by the gel method. Its thermal decomposition reaction was studied in a dynamic atmosphere of dry nitrogen using TG-DTG. The thermal decomposition processes of the complex were determined and their kinetics were investigated. The kinetic parameters were obtained from analysis of the TG-DTG curves by integral and differential methods. The most probable mechanism function was suggested by comparison of the kinetic parameters. Mathematical expressions for the kinetic compensation effect were derived. Some valuable results have also been obtained and are discussed.
