Knowing accurate saturated vapor pressures of explosives at ambient conditions is imperative to provide realistic boundaries on available vapor for ultra-trace detection. In quantifying vapor content emanating from low-volatility explosives, we obser

Cellulose acetate butyrate (CAB) was flash-pyrolyzed at 600–1000°C/s to temperatures in the 460–600°C range under 1 atm Ar. By using nonnegative least squares analysis of the data, 11 specific products (CO, CO2, acids, esters, ketenes, aldehyde

During the combustion of solid propellants, explosives, or pyrotechnics, the condensed phase experiences heating rates that may exceed 20,000 K/s. At such high heating rates, the thermal decomposition behavior of the energetic material could be affec

Controlled flash pyrolysis is described of hydroxyl-terminated polybutadiene (HTPB), cellulose acetate butyrate (CAB), and polyethyleneglycol (PEG). Real-time detection of the vaporized products (FTIR spectroscopy) and thermal events of the sample (c

The principal binder of many LOVA propellants is cellulose acetate butyrate (CAB). By the use of T-Jump/FTIR spectroscopy, CAB was flash-pyrolyzed to set temperatures in the 465–600°C range, while rapid-scan IR spectra were used to identify the ma
