Laboratory and Pilot Scale Detoxification of VX in Acidic Media Using Chlorine Gas.

摘要

The purpose of this investigation was to study the possibility of destroying bulk quantities of VX dissolved in acid solution by sparging with chlorine gas. Laboratory experimentation using a batch process demonstrated the feasibility of chlorine detoxification and indicated the optimum conditions for detoxification. Three laboratory systems were scaled up for evaluation of detoxification efficiency on a pilot scale,using 100-lb charges of VX. The most efficient system studied in both laboratory and pilot work was one in which one volume of VX was dissolved in three volumes of 1.5normal hydrochloric acid solution,followed by sparging with a stoichiometric amount of chlorine gas. Major reaction products included N,N-diisopropyltaurine,ethyl methylphosphonic acid,hydrochloric acid,and N,N'-dicyclohexylurea (from the VX stabilizer). It was concluded that the chlorination of VX in acid solution was an effective method of destroying bulk quantities of VX.
