Abstract

The method of programmed linear variation of the temperature of a substance with massspectrometric detection of the components was applied to the investigation of the kinetics and mechanism of the thermolysis of cyanocobalamin (vitamin B12). The frequency factors and the activation energies of the decyanation reactions were obtained.
