A method for producing glycyl ether of a polyhydric phenol by reacting a polyhydric phenol with epichlorohydrin and an alkali metal hydroxide characterized by heating a solution of said polyhydric phenol in an excess of epichlorohydrin and adding a hemimolar equivalent of an aqueous solution. Concentrate the said alkali metal hydroxide while maintaining the solution at full reflux and then adding a hemimolar equivalent of said concentrated aqueous solution at the same time that the water and epichlorohydrin vapors are removed by distillation from the reaction mixture and removing the water from the vapors and return the epichlorohydrin to the reaction mixture to be subjected to a new cycle.
