  This invention is a method of reducing the hydrolyzable chloride content of an epoxidation product, without substantially altering it otherwise. The method is characterized by comprising the steps of (1) providing a two-phase mixture of (a) an organic phase which is a solution of said product in a solvent having the characteristics of a blend of from 40 to 55 weight percent methylethylketone and from 60 to 45 weight percent toluene, and (b) an aqueous solution of from 1 to 3 equivalent of base per equivalent of hydrolyzable chloride in said product, the amount of water in said solution being such that the base concentration therein will not be less than equivalent to 4 weight percent aqueous NaOH after completion of the following step, and (2) intimately intercontacting said phases, at an elevated temperature, until the hydrolyzable chloride content of said product has decreased to a satisfactory extent. The method considerably reduces the hydrolyzable chloride content of epoxidation products prepared from epichlorohydrins and phenols, aromatic amines and heterocyclic compounds containing >NH groups in the ring.
