Thermal decomposition of N-substituted N-methylnitroamines

Thermal decomposition of the N-methylnitroamines based on azoles in the liquid phase proceeds as a first-order reaction and is limited by the homolysis of the N-NO2 bond. The reaction rate is affected by the steric effect of the azole substituent. The activation parameters for the limiting stage of thermal decomposition were determined, and correlations between the logarithm of the rate constant, activation energy, and the steric constant Es of the substituent were elucidated.
