Multinuclear NMR (31P and 13C) was used to monitor the reactions--of GA, GB, GD, VX, and O,S-diethyl methylphosphonothiolate (DEMPS) with DS2. The organophosphorus products from the primary and secondary reactions in DS2 were identified. Variations in the reaction profiles as a function of time and added water provided valuable insight into the mechanism of action of DS2 and the important factors influencing its effectiveness. It was found that low concentrations of water (5%) had no measurable effect on the efficacy of DS2 to decontaminate the agents. However, at higher concentrations of water (50%), the nonaqueous chemistry of DS2 was destroyed and hydrolysis behavior predominated.
