PROCESS FOR PREPARING FLUORINE-CONTAINING PROPENES CONTAINING 2,3,3,3-TETRAFLUOROPROPENE AND 1,3,3,3-TETRAFLUOROPROPENE

摘要

The present invention provides a process for preparing fluorine-containing propenes containing 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene, including reacting 1,1,1,3-tetrachloro-3-fluoropropane represented by the formula CCl3CH2CHClF and anhydrous hydrogen fluoride in the gas phase in the presence of a catalyst. The process of the invention produces fluorine-containing propenes containing 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene in an industrially applicable, simple and effective manner.
