We are investigating the interaction of dimethyl methylphosphonate and diisopropyl methylphosphonate, both simulants of chemical warfare agent, on anhydrous and natural kaolinite and compare the results with those of these two simulants on titania. Infrared spectroscopy indicates the presence of multiple rotational isomers that have different interactions with the surface. Initially, we observe physisorbed species which desorb again over time. However, at later times we observe a chemisorbed species which appears stable.
Using kinetic FTIR, we have measured the infrared spectra of diisopropyl methylphosphonate (DIMP), a chemical warfare agent (CWA) simulant, and its decomposition products under a variety of heating conditions. DIMP and its phosphorus-containing decomposition products have many overlapping spectral features, all of them changing with temperature, making unique identification of individual compounds exceedingly difficult. We have analyzed these spectra and identified spectral features that allow us to identify specific compounds.
