ResumoAbstract A chemical destruction method based on the reaction of poly(ethylene glycol)/KOH with polychlorinated biphenyls (PCB) has been tested for PCB liquids produced in Czechoslovakia ( Delor 103 and 106 ). It was found that while the method can be used sucessfully for the destructive removal of the higher chlorinated Delor 106 from nonpolar hydrocarbon liquids, the low reactivity of the reagent with the di- and some trichlorinated biphenyls present in Delor 103 prevents its efficient application in the more frequent cases of the purification of PCB - contaminated mineral oils.
