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.

Removal of PCBs and other halogenated organic compounds from organic

Organosulfur compounds containing a C-S bond are decomposed by reaction with a reagent made from an alkali metal, a polyglycol or a monoalkyl ether thereof and oxygen, which effects decomposition by cleavage of the C-S bond.

Reagent and method for decomposing organosulfur compounds

A composition of matter in the form of a coordination complex which is the product of the reaction of an alkali metal or alkali metal hydroxide of a polyglycol or a polyglycol monoalkyl ether and oxygen having utility as a decomposition reagent for halogenated organic compounds.

Composition for decomposing halogenated organic compounds

A reagent comprising the product of the reaction of an alkali metal hydroxide with a polyglycol or a polyglycol monoalkyl ether and oxygen, effects complete decomposition of halogenated organic compounds, such as polychlorinated biphenyls (PCBs), when mixed therewith in the presence of oxygen.

Method for decomposition of halogenated organic compounds

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.

Removal of PCBS and other halogenated organic compounds from organic

A reagent, comprising the product of the reaction of an alkali metal with a polyglycol or a polyglycol monoalkyl ether and oxygen, effects complete decomposition of halogenated organic compounds, such as polychlorinated biphenyls (PCBs), when mixed therewith in the presence of oxygen.
