title: Solvent Effects on the Reactions of the Nerve Agent VX with KF/Al2O3: Heterogeneous or Homogeneous Decontamination?
abstract: Solvent effects on the reactions of the extremely toxic nerve agent VX with KF/Al2O3 powder were explored. Small quantities of water or methanol (5-10 wt %), which effectively mobilized all components while maintaining the heterogeneous nature of the reaction, promoted much faster rates than those obtained with larger quantities. Any amount of acetonitrile resulted in extremely slow transformations. Surprisingly, 5-50 wt % of heptane led to fast reactions due to the combination of its ability to mediate fast diffusion of VX and a MAS centrifugation effect.
