摘要：
The thermal decomposition of bis-R-substituted gem-dinitroethyl-N-nitramines in diphenyl ether solution was studied by a manometric method combined with mass spectrometry and photocolorimetry. The reaction is described by a first order equation and is not complicated by chain and heterogeneous processes. The rate-determining step of the process is the homolysis of the C NO2 bond in the gem-dinitro group. The kinetic parameters of the rate-determining step were determined. The influence of the structure on the reactivity of the investigated compounds was analyzed. Linear relationships were found between the rate constant, the activation energy of thermal decomposition, and the steric constants of the a-substituent of the reaction center.
