Abstract

Due to extreme toxicity of chemical warfare (CW) agents, experiments to study their combustion behavior are carried out using simulants. Organo Phosphorus Compounds (OPC's) are commonly used as CW simulants and are also considered as flame retardants. In this study, gas phase absorption cross section of a CW simulant - Tri-methyl Phosphate (TMP) has been measured at 2 cm-1 resolution, and within 750-3500 cm-1 wavenumber range (2.85-13.33µm). The measurement was carried out at 295 K using in-house built FTIR sample cell with Ge-windows. Due to low vapor pressure of these compounds, a novel experimental technique has been developed in which liquid sample was taken in a boat and placed inside the sample cell. Current measurement were taken when the concentration of TMP inside the sample cell reached a stable value, i.e. the saturation vapor pressure at ambient condition. This quantitative gas-phase spectra is very important in setting up laser based monitoring schemes in combustion reactors.
