ABSTRACT:
A process and apparatus for making a low salt epoxide is disclosed. The process comprises feeding a halohydrin solution into one compartment of a dialysis cell separated from a hydroxide dialyzing solution in a second compartment by an anionic membrane. An effective hydroxide concentration gradient across the membrane induces hydroxyl ion exchange for excess anions from the halohydrin solution so that electroneutrality across the membrane can be maintained.
