Abstract
Organic functional fluids containing halogenated organic compounds present as contaminants therein are treated in an inert atmosphere with a NaPEG decomposition reagent which is prepared in an inert atmosphere, thereby to produce a functional fluid phase substantially free of the halogenated organic compound and a reagent residue phase containing a derivative of the contaminant having a reduced halogen content. The latter may be further dehalogenated by reacting the reagent residue with a NaPEG reagent in the presence of oxygen.
