Critical Analysis of Nitramine Decomposition Data: Product Distributions from HMX and RDX Decomposition

Abstract

A summary of a critical interpretative literature review on product distributions from HMX and RDX decomposition is presented. Principal products formed include N2O, N2, H2CO, CO, CO2, and NO; these and a number of other products such as HCN, HCOOH, NO2(-), NO3(-), hydroxymethyl formamide, H2, and H2O are tabulated. NO2 appears to be formed, but is so reactive that many failures to report it may well be due to the fact that is disappears too rapidly due to further reaction. Relative amounts of HCN and NO2 may increase at high temperature, while H2CO, etc., decreases. A discussion of the first step of the decomposition is presented. A discussion of some possible unimolecular and bimolecular follow-up steps is also presented; among other things the N2/N20 ratio and some possible mechanisms for formation of molecular nitrogen (N2) are discussed. In conclusion, it is pointed out that possibly the most useful aspect of thermal decomposition studies at low temperatures and pressures is to elucidate the types of chemical deposition processes involved, including minor ( at low temperatures and pressures) pathways, in addition to the principal ones. Informed extensive of this body of knowledge to combustion conditions could then provide the basis for improved understanding and control of combustion processes and operational properties such as stability, sensitivity, and burning rate behavior.
