摘要：

Thermal decomposition kinetics of bis-gem-dinitroethyl substituted compounds based on N-nitraminoacetic acid is studied. Structural and kinetic patterns are revealed and a chemical mechanism of decomposition reaction is established, including the primary homolysis of C-NO2 bond in the gem-dinitroethyl fragment. The activation parameters are defined for the initial reaction. The reactivity of the studied compounds was analyzed and quantitative correlations between the logarithms of the rate constant, the activation energies and the steric constants of substituents in the gem-dinitroethyl group were found.
