Abstract
Macrokinetic regularities of high-temperature transformations of a number of s-triazine derivatives containing azide, propynyl oxide and propynyl amine functional groups have been investigated. It has been shown that these compounds are capable of self-propagating high-temperature transformation (combustion) in the absence of an external oxidizer. Linear combustion rates in a nitrogen environment are proportional to the enthalpies of formation of the corresponding s-triazine derivatives. Diazide derivatives burn with the highest rates, lower combustion rates correspond to compounds containing three acetylene groups. Thermal decomposition of azidoacetylene derivatives of s-triazine has been studied using thermogravimetry and differential scanning calorimetry. Thermal analysis has shown that the most stable compound in the studied series of samples is the compound containing three propynyl amine groups, the least stable are the diazide derivatives of s-triazine.
