1112--2- 2333- A PROCESS FOR DEHYDROCHLORINATING 1112-TETRAFLUORO-2-CHLOROPROPANE TO 2333-TETRAFLUOROPROPENE IN THE PRESENCE OF AN ALKALI METAL-DOPED MAGNESIUM OXYFLUORIDE CATALYST AND METHODS FOR MAKING THE CATALYST

摘要

A process for producing fluorinated olefins is provided. The process comprises dehydrochlorinating a hydrochlorofluorocarbon having at least one hydrogen atom and at least one chlorine atom on adjacent carbon atoms in the presence of a catalytically effective amount of a catalyst composition. The catalyst composition is expressed as follows:N wt% MX / M'O_YF_ZWherein 0 y 1, 0 z 2, and y + z / 2 = 1 in the formula; M is Li⁺, Na⁺, K⁺, Rb⁺, And Cs⁺An alkali metal ion selected from the group consisting of: X is F^-, Cl^-, Br^- And I^-And M 'is a bivalent metal ion; Wherein n is selected from the group consisting of MX and M'O_YF_ZAbout 0.05-50 wt% MX based on the total weight of the composition, wherein y and z are M'O_YF_Z/RTI is the molar fraction of oxygen and fluorine, respectively.A method for producing the catalyst composition is also provided.
