摘要：
A fluorination catalyst based on of an amorphous Cr (III) compound and on a compound of another metal selected from Mg, Ca, Sr, Ba, Sc, Ti and Zr, wherein the atomic ratio of Cr/other metal is between 50:1 and 1:1, said compounds are supported on a AlF.sub.3 support and being prepared by impregnating the support with a concentrated aqueous solution containing a soluble Cr (III) salt and a soluble salt of the other metal. The catalyst can be used in gaseous phase reactions.
