Abstract
AbstractThe thermal characteristics of tetraformaltrisazine and formalazine were studied for the first time using differential thermal analyser, thermogravimetric analyser and mass spectrometer. Kinetic analysis of the degradation of each of these compounds and the effect of enveloping atmosphere on the degradation are reported. Degradation mechanisms have been postulated. Based on values of activation energy and supported by evidences made available by mass spectrometric studies it has been concluded that the second stage of thermal degradation of tetraformaltrisazine and formalazine in inert atmosphere may be ascribed to N‐N bond rupture.The heats of degradation of tetraformaltrisazine and formalazine were determined by differential scanning calorimeter. The Values obtained are + 360.4 ± 0.5 cal/g and + 105.8 ± 0.7 cal/g respectively.
