Title: Thermal decomposition of energetic materials: Temporal behaviors of the rates of formation of the gaseous pyrolysis products from condensed-phase decomposition of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine

Abstract

The temporal behaviors of the rates of formation of the gaseous products from the pyrolysis of HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) are determined by simultaneous thermogravimetric modulated beam mass spectrometry (STMBMS). The gaseous products formed from the pyrolysis of HMX, and its deuterium- and {sup 15}NO{sub 2}-labeled analogues, between 210 and 235{degree}C are H{sub 2}O, HCN, CO, CH{sub 2}O, NO, N{sub 2}O, CH{sub 3}NHCHO, (CH{sub 3}){sub 2}NNO, 1-nitroso-3,5,7-trinitro-1,3,5,7-tetrazocine (ONTNTA), and their isotopic analogues. In addition, a nonvolatile residue (NVR) is formed. The NVR is a polyamide that decomposes between 250 and 780{degree}C producing NH{sub 3}, HCN, HNCO, H{sub 2}NCHO, CH{sub 3}NHCHO, and products that include long-chain hydrocarbons. The temporal behaviors of the rates of gas formation of the pyrolysis products along with the macroscopic and microscopic structure of the NVR indicate that complex physical processes and chemical mechanisms within the condensed phase of HMX control the decomposition.
