Abstract
There is provided methods for making a catalyst composition represented by the formula MX/M′F2 wherein MX is an alkali metal halide; M is an alkali metal ion selected from the group consisting of Li+, Na+, K+, Rb+, and Cs+; X is a halogen ion selected from the group consisting of F−, Cl−, Br−, and I−; M′F2 is a bivalent metal fluoride; and M′ is a bivalent metal ion. There is also a method for making a fluorinated olefin.
