Abstract
The preparation, structure, and properties of solid inorganic materials containing at least copper, chromium, aluminum, boron and oxygen which new materials have a characteristic X-ray diffraction pattern are described. Also described is the use of such materials in catalytic compositions for the conversion of organic compounds. In particular, new compositions comprising material having a structure EQU Cu.sub.2-x Cr.sub.y Al.sub.6-y B.sub.4 O.sub.17 M.sub.m M'.sub.n where M is a divalent metal, M' is a monovalent metal, m is a number in a range from 0 to 0.8, n is a number in a range from 0 to 1.6, X is a number in a range from 0 to 0.8 and is equal to the sum of m and n/2, and y is a number in a range from 0.01 to 3, having a characteristic X-ray diffraction pattern are described as well as the use of such materials in various catalyzed processes including dehydrogenation of hydrocarbons and oxygen-containing hydrocarbons.
