1. A method of making epoxides, the method comprising:
in a reactor comprising an anode and a cathode separated by an ion exchange membrane, and containing a reactant comprising a hydroxy-alkane; and a solution comprising water and halogen ions, and;
(a) applying a potential across the anode and the cathode such that a halogenated intermediate is produced at the anode as an anolyte and hydroxyl ions are produced at the cathode as a catholyte; and
(b) combining the anolyte and the catholyte to yield an epoxide.
