Abstract:

The T-jump/FTIR(Fourier transforminfrared) spectroscopy technique was used to study the flash pyrolysis of metallic (Li, Na, K, Mg) compounds of trinitrophloroglucinol (TNPG, 2,4,6-trinitro-1,3,5-trihydroxybenzene). Volatile metallic compounds liberated during the flash pyrolysis of trinitrophloroglucinol metallic (Li, Na, K, Mg) compounds were determined. A curve showing the concentration of gas with time during flash pyrolysis was also derived. A qualitative and quantitative analysis of the main IR-active gas products resulted from the thermal decomposition was carried out. The REAL program was used to study the components of the combustion products, reaction thermodynamics and the burning temperature of trinitrophloroglucinol metallic (Li, Na, K, Mg) compounds, which were compared with experimental results gained fromthe T-jump/FTIR spectroscopy technique.

Key words: T-jump/FTIR spectroscopy, Trinitrophloroglucinol compound, Flash pyrolysis, REAL program
