The decontamination of 2-Chloroethylphenyl sulfide (CEPS), a simulant for HD mustard gas, with a methanolic solution of tetramethylammonium hydroxide in the ionic liquid DMPITf2N was investigated. The reaction rate was followed using liquid chromatography/time of flight mass spectrometry (LC/MS-TOF). The optimum reactant to simulant ratio was found experimentally to be greater than 2.5:1. Simulants for VX (BEHP) and Sarin (DFP) also reacted rapidly in the same matrix. The ionic liquid was recovered following solid-phase extraction.
