Abstract
Organic functional fluids containing halogenated organic compounds present as contaminants therein are treated with a NaPEG decomposition reagent in an inert atmosphere to produce a functional fluid phase substantially free of the halogenated organic compound and a reagent residue phase containing a partially dehalogenated organic derivative therein. The latter may be further dehalogenated by reacting the reagent residue with oxygen.
