Catalytic activity of   modified  natural zeolite – сlinoptilolitе by Sn²⁺, Pd²⁺, Cu²⁺ and Fe³⁺ cations in vapour phase reaction of oxidation of cyclohexanol  by oxygen of air into cyclohexanone have been studied. On the basis of the experimental investigation it is shown that natural сlinoptilolitе modified both by one of here combination in it of tin, palladium and copper of 0.5, 0.15 and 0.5 mas.% in number relatively is an active and selective catalyst of this reaction.
