Thermal decomposition of energetic materials 21. The effect of the backbone composition on the products evolved upon rapid thermolysis of linear nitramines

Abstract

High-rate thermolysis data for two primary linear nitramines and three secondary linear nitramines are compared to evaluate the effect of differences in the composition of the backbone on evolved gas products .The primary nitramines retain the NN bonds but undergo CN bond fission, while the secondary nitramines exhibit much more NN bond fission. The NCH 2N backbone unit in nitramines is less thermally stable than the N(CH 2) 2N unit. A comparison of a compositionally similar cyclic and acyclic nitramine pair leads to the conclusion that cyclization hardly influences the thermolysis products or their relative concentrations.
