A process for making a fluorinated olefin, comprising dehydrochlorinating a hydrochlorofluorocarbon having at least one hydrogen and at least one chlorine on adjacent carbons in the presence of a catalytically effective amount of a catalyst composition represented by the following:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ MX/M'F 2
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'F 2 is a bivalent metal fluoride; and
M' is a bivalent metal ion. |
