Abstract

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.
