ABSTRACT:
A combination of zinc oxide and zinc bromide employed as a catalyst for the reaction between phenol and a 1,2-dihaloethane wherein the halogen is chlorine, bromine or iodine provides for increased reaction rates as compared to the use of either zinc compound separately as catalyst and elimination of the induction period characteristic of the reaction when zinc oxide is used as the catalyst.
