CATALYSED SYNTHESIS OF FLUORINATED ALKENES AND FLUORINATED ALKENE COMPOSITIONS

摘要

A method of producing a fluoroolefin includes contacting a compound of formula (1), R_fCX₁=CHCF₃, with a fluorinated ethylene compound of formula (2), CX₂X₃=CX₄X₅ in the presence of a catalyst. In the compound of formula (1), R_f is a linear or branched C₁-C₁₀ perfluorinated alkyl group and X₁ is H, Br, Cl, or F. In the compound of formula (2), X₂, X₃, X₄, and X₅ are each independently H, Br, Cl, or F and at least three of X₂, X₃, X₄, and X₅ are F. The resulting composition comprises a compound of formula (3), R_f(CF₂)_nCX₆=CH(CF₂)_mCX₇X₈CFX₉X₁₀. In the compound of formula (3), X₆, X₇, X₈, X₉, and X₁₀ are each independently H, Br, Cl, or F, and the total number of each of H, Br, Cl, and F corresponds to the total number of each of H, Br, Cl, and F provided by the compounds of formulae (1) and (2).
