Chromic anhydride (I) [1333-82-0] was applied to a nonporous support from the gas phase with subsequent oxidn. with O in vacuo. The activity of the catalyst was increased by treating with CO [630-08-0] at 200-600° and 0.1-1.0 abs. atm with subsequent removal of the unreacted CO by heating in vacuo or by blowing with an inert gas at 200-600°.
