Abstract

Ionic liquids have the potential for being ideal alternatives for organic solvents in chemical warfare agent reactions and demilitarization processes. They are considered to be an excellent substitute, because of their extraordinarily wide liquid range, low melting points, chemical and thermal stability, high conductivity, and nonvolatility. In addition, many have excellent hydrophobic properties and immiscibility with water and offer the opportunity to isolate the chemical agents and reaction products from the environment. In this report, we describe a two-step process in which chemical warfare simulants are reacted with hydrogen peroxide (H2O2) followed by basic methanol in a common ion binary ionic liquid that consists of 1,2-dimethyl-3-propylimidazolium bis(trifluoromethylsulfonyl)amide and copper(II) bis(trifluoromethylsulfonyl)amide. The chemical agent simulants used in this study are diisopropylfluorophosphate, bis(2-ethylhexyl) phosphite, and 2-chloroethylphenyl sulfide, which simulate agents GB, ...
