Abstract
We have found that polychlorinated biphenyls (PCB's) and other unactivated chlorobenzenes react with poly (ethylene glycols) and potassium hydroxide under mild conditions. Complete reaction with PEG occurs at 75–120°C in under two hours, to produce aryl polyglycols, the products of nucleophilic aromatic substitution. This reaction has been applied to the destruction and removal of PCB's from non-polar media, including transformer oil.
