KINETICS AND MECHANISM OF THERMAL DECOMPOSITION OF 5-SUBSTITUTED DERIVATIVES OF DINITROMETHYL-2-METHYLTETRAZOLE

摘要

5-Substituted derivatives of 5-dinitromethyl-2-rhethyltetrazole in melt and in solution of dibutyl phthalate decompose homolytically with the primary break of C-NO2 bond in dinitromethyl group.Introduction of volume substituents (CI, Br, I, etc.) into the dinitromethyl group leads to increase in the rate constants of decomposition. The activation parameters for the primary (limiting) stage are found. It is shown, that rate constants and activation energy of decomposition of dinitroderivatives of tetrazole correlate with the steric constants of substituents.
