Abstract
Epoxidate from the molybdenum catalyzed epoxidation of an olefin such as propylene with a hydroperoxide such as ethylbenzene hydroperoxide is treated with 2 to 15 times the stoichiometric equivalent of aqueous base such as sodium hydroxide to form Na.sub.2 MoO.sub.4 and the resulting mixture is phase separated to separate an organic phase reduced in molybdenum and a net aqueous stream containing removed molybdenum, the mass ratio of the organic phase to the net aqueous stream being 450-3,000/I.
