Three-liquid-phase epoxidation of perfluoroolefins.

摘要

A process for converting a perfluoroolefin to its epoxide by agitation at reaction conditions that maintain three liquid phases - an aqueous phase comprising hypohalite ions, an epoxide phase comprising the bulk of the epoxide and essentially no phase transfer catalyst, and a reaction phase comprising an organic liquid in which a phase transfer catalyst is soluble and which has a higher affinity for perfluoroolefin than for its epoxide (partition coefficient greater than 1.3).
