Detoxification of O, S-diethyl methyl phosphonothiolate (OSDEMP), a simulant of VX, by N, N-dichlorourethane as an effective decontaminating agent

N, N-Dichlorourethane has been synthesized and characterized by FT-IR, NMR. Efficiency of this compound as decontaminant has been evaluated by the reaction of O, S-diethyl methyl phosphonothiolate (OSDEMP), a simulant of VX at RT. The decontamination reaction has been monitored by gas chromatography (GC) and the products have been identified by GC-MS.
