Abstract
The method for preparing carbonyl compounds according to the present invention comprises a vapor phase oxidizing dehydrogenation of C.sub.1 -C.sub.4 alcohols at a temperature ranging from 500.degree. to 700.degree. C. in the presence of a silver catalyst, wherein silver is supported on a carrier having a crystalline structure incorporating alumina and silica in the form of cristobalite.
