ABSTRACT:
A process for the production of oximes which comprises contacting, in the vapor phase, a primary saturated aliphatic or alicyclic amine of 2 to 12 carbon atoms with an elemental oxygen gas in the presence of an effective amount of a catalyst comprising an alumina or oxygen-containing tungsten substance on a metal oxide support using temperatures between about 130.degree. and 230.degree. C. at atmospheric pressure is disclosed. Preferred alumina catalysts are alumina xerogels, .gamma.-alumina and acidic, fluorinated alumina. Preferred oxygen-containing tungsten catalysts are WO.sub.3 on .gamma.-alumina or WO.sub.3 on alumina xerogels.
