Claims3
A continuous method for the destruction of polyhalogenated biphenyls which comprises injecting said biphenyls into a continuously circulating hydrocarbon oil to an initial concentration of from about 1% to about 3% by weight and effecting reaction in the oil circulating at about 5 to about 25 gallons per minute at a temperature above about 75.degree. up to about 150.degree. C. with a dispersion of sodium in a hydrocarbon oil wherein the particle size of the sodium particles is from about one to about ten microns, separating the particulate solids that are formed and recycling said hydrocarbon oil.
