KINETICS AND MECHANISM OF THERMAL DECOMPOSITION OF R-SUBSTITUTED DERIVATIVES OF 1,1-DINITROMETHYL-3-NITRO-1,2,4-TRIAZOLE

摘要

Thermal decomposition of 1-R-1,1-dinitromethyl-3-nitro-1,2,4-triazole, where R = H, F, CH_3, CH_2N(NO_2)CH_3, NO_2, Cl, Br, I, is studied in static and dynamic conditions in melt, solution and solid phase. The structural and kinetics laws and the mechanism of thermal decomposition are discovered. The activation parameters for the limiting stage are defined. The analysis of reactivity of the studied compounds is made. The quantitative relationships between the logarithm of the rate constant, activation energy, the temperature of intensive decomposition and the steric constant of substituent in geminal dinitromethyl function are found.
