Olefinically unsaturated hydrocarbons are prepared from corresponding paraffinic hydrocarbons, in particular propylene is prepared from propane, by dehydrogenation over a catalyst comprising an oxide of a transition metal of group IV B of the Periodic Table, eg. TiOor ZrO, and possibly at least one element selected from among elements of transition group VIII, eg. palladium, platinum or rhodium, and/or an element of transition group VI, eg. chromium, molybdenum or tungsten, and/or rhenium and/or tin and possibly a compound of an alkali metal or alkaline earth metal, a compound of main group III or transition group III or zinc.

The disclosure is directed to a process for preparing an oxidic catalyst comprising copper in an oxidation state >0, which comprises treating a solid oxidic support material with an aqueous solution comprising at least one copper salt and at least one organic water soluble polymer which binds copper ions coordinatively in a concentration of from 0.1 to 100 g/l and then calcining, to the catalyst obtainable by this process and also to a process for dehydrogenating secondary alcohols to ketones using the catalysts, especially for dehydrogenating cyclohexanol.
