Preparation of hydrofluoroolefins by dehydrofluorination

摘要

A dehydrofluorination process is disclosed for making hydrofluoroolefins of the structure RfCH=CHRf, wherein each Rf is independently a perfluoroalkyl group or a perfluoroalkyl group having a terminal hydrogen. The process involves reacting RfCH2CHFRf with a basic aqueous solution to produce a product mixture comprising RfCH=CHRf.
