Catalyst for dehydrogenation of oxygen containing derivatives of the cyclohexane series into corresponding cyclic ketones and/or phenols

Abstract

A catalyst for dehydrogenation of oxygen-containing derivatives of the cyclohexane series of the general formula: ##STR1## wherein R.sub.1 is hydrogen or a C.sub.1 -C.sub.4 alkyl; R.sub.2 and R.sub.3 are radicals having the same or different meanings: --H, --OH, .dbd.O, provided that R.sub.2 and R.sub.3 are not simultaneously hydrogen and R.sub.1, R.sub.2 and R.sub.3 are attached to different carbon atoms of the cycle, into the corresponding cyclic ketones and/or phenols containing the following components, percent by weight: ______________________________________ nickel 15 to 55 promotor-germanium and/or lead 0.2 to 8.0 inert carrier 84.8 to 37.0 ______________________________________ and an atomic ratio of nickel to the promotor is within the range of from 15:1 to 410:1 respectively. The catalyst can additionally contain a salt of an alkali metal and a mineral acid in an amount of from 0.01 to 1.0% by weight.
