Two novel cobalt (Ⅱ) schiff base complexes, salicylaldehyde L-methionine-hydrated cobalt (Ⅱ) (1), o-vanillin L-methionine-cobalt hydrate 2) The properties of the complexes were studied by means of elemental analysis, infrared spectroscopy, thermal analysis and other testing methods, and the composition of the complexes was determined. The saturated oxygen uptake of the complex at different temperatures in acetonitrile solution was determined by the gas absorption device, and the equilibrium constants and thermodynamic parameters of the oxygenation reaction were obtained. The effects of temperature and ligand structure on the oxygenation performance of the complex were also discussed. The thermal stability and non-isothermal decomposition kinetics of the complexes were studied by TG-DTG method. The first step of the thermal decomposition reaction mechanism of the two complexes was deduced by using the method of integration and differentiation. Decomposition reaction kinetic parameters and their kinetic equations.
