Abstract

A process for producing epoxide, the process including contacting an organic phase including at least one halohydrin(s) with at least one aqueous phase including a base in a plug-flow mixer/reactor system to disperse the organic phase in the aqueous phase via a mixing device imparting a power-to-mass ratio of at least 0.2 W/kg to convert at least a portion of the at least one halohydrin to an epoxide.
