Time-resolved analytical pyrolysis studies of nitramine decomposition with a triple quadrupole mass spectrometer system

The study of thermal decomposition of RDX by corona discharge-ion mobility spectrometry-mass spectrometry

“…The ions m/z 46 Da have been observed in many previous studies and therefore we assigned it according to them to NO 2 − [16,10]. An initial step for its generation is the cleavage of N-NO 2 bond in RDX [16].…”

“…It is stable in storage and considered as one of the most brisant military explosives. Therefore, many studies have been dedicated to its ignition, decomposition and combustion behaviour [16].…”

“…RDX has been examined over selected thermal ranges using a pyrolysis technique interfaced to an atmospheric pressure chemical ionization tandem mass spectrometer MS-MS system by Liebman [16]). Another research of RDX has been focused on using pyrolysis-gas chromatography (PGC) and pyrogenic products of this explosive were identified by pyrolysis capillary gas chromatography-mass spectrometry (PCGC-MS) [15].…”

Pyrolysis GC-FTIR studies of a LOVA propellant formulation series

“…Examination of go/no-go ignition times as a function of laser flux suggests that samples can be divided into three groups (see Figures 11-13 any, of these products may serve as catalysts has not been determined, though formaldehyde has been reported to catalyze the thermal decomposition of RDX (Batten 1971(Batten a, 1971Liebman et al 1987). Further evidence of catalysis by plasticizer and/or plasticizer decomposition products is the observation that wh~!e triazine is produced for HMX formulations and unplasticized RDX formulations in low temperature experiments, as well as for all HMX and RDX formulations in high temperature experiments, no triazine is produced for plasticized R :)X formulations at low temperature.…”

Combustion Mechanisms of Very High Burn Rate (VHBR) Propellant. Phase II.

“…These concerns also led to a study of formulations with improved safety characteristics, as well as a more detailed examination of the factors which may contribute to VHBR behavior. Furthermore, examination of the pyrolysis products generated when HMX and RDX were heated while in contact with HIVELITE showed that the boron hydride modified the decomposition of these oxidizers [22,23,24], thereby producing pyrolysis products typically found at much higher temperature levels. In addition, RDX and HMX begin decomposing at lower temperatures when in the presence of HIVELITE salts than when tested alone.…”
