Method for removing polyhalogenated hydrocarbons from non-polar organic solvent solutions
In a method for reducing the concentration of polyhalogenerated aromatic hydrocarbons present in a non-polar inert organic solvent solution comprising reacting in a reactor the polyhalogenated aromatic hydrocarbon with a reagent comprising an alkali metal hydroxide and a glycol selected from the group consisting of polyalkylene glycol and monocapped polyalkylene glycol ether, the improvement is described comprising maintaining the reaction mixture under substantially water-free conditions until the concentration of polyhalogenated aromatic hydrocarbons has been reduced below about 2 ppm, and then adding to the reaction mixture at least about 0.25% by weight water, whereby sticky viscous solids are removed from the reactor.
