Patent ID: 8053612

Claim:
A process for making a fluorinated olefin, comprising: 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 represented by the following: n wt. % MX/M′O y F z wherein 0<y<1 and 0<z<2 and wherein y+z/2=1; wherein 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′ is a bivalent metal ion; wherein n is a weight percentage of about 0.05% to about 50% MX based on the total weight of the MX and M′O y F z ; and wherein y and z are the mole fractions of oxygen and fluorine in M′O y F z , respectively.
