<p>C2 and C3 alcohols and their ether and ester derivatives are contacted 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 preferably 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, on a support, so that the contact mass has a surface area less than about 1,500m<2> per gram; integration of the method with the distillation of isopropyl alcohol streams is described.</p> |
