ABSTRACT OF THE DISCLOSURE Methods for deodorizing lower alcohols such as ethanol and isopropyl alcohol and their oxy derivatives such as ethers and eaters are disclosed, including contacting these compounds with a deodorizing contact mass comprising metals and/or metal oxides, preferably of the metals of Group IB, VB, VIB, VIIB, and VIII of the Periodic Table, where the metal oxides are at least partially reduced and the deodorizing contact mass has a minimum particle dimension of greater than about .254 mm so as to be in a form suitable for use in a fixed bed contacting process. In a preferred embodiment, isopropyl alcohol is deodorized employing such deodorizing contact masses, preferably comprising Group VIII metals such as nickel, iron, cobalt and the like, on a support, so that the contact mass has a surface area less than about 1,500m2 per gram.
