ABSTRACT:
There are a catalyst for producing 1,1,1,2-tetrafluoroethane represented as Cr.sub.a L.sub.b M.sub.c O.sub.x F.sub.y wherein L is Mg or Ca; M is one element selected from a group consisting of Ce, Ni, Zn, and Al; and each value of a, b, c, x and y are all between 0 and 2, and a method for preparing the same comprising the steps of: producing an admixture of a composition comprising chromium hydroxide hydrate and magnesium chloride or calcium chloride in a weight ratio of Cr to Mg or Ca ranging from 1:0.3 to 1:10 with an aqueous metal salt solution; reacting the admixture with an aqueous HF solution to give a paste; and sintering the paste.
