|
The catalytic degradation of the nerve agent VX (O-ethyl S-2-(diisopropylamino)ethyl methylphosphonothioate) by water-swelled polymer-supported ammonium fluorides is described. VX (0.06-0.53 mole/mole F-) is rapidly degraded (t1/2 ~ 10-30 min) forming the "G-analogue" (O-ethyl methylphosphonofluoridate), which hydrolyses (t1/2 ~ 1-1.5 h) to the non-toxic EMPA (ethyl methylphosphonic acid). The toxic desethyl-VX is not formed. The catalytic effect of fluoride is maintained even when six equivalents of VX are loaded. GB (O-isopropyl methylphosphonofluoridate) and desethyl-VX agents are also degraded under these conditions. |
