ABSTRACT:
A liquid mixture of normal butane and isobutane is catalytically oxidized at 15-45% conversion of the isobutane per pass at conditions favoring selective oxidation of the isobutane with minimized oxidation of the normal butane, thereby eliminating the need for superfractionation for ultrapurification of the isobutane prior to the oxidation step. Conditions include 260.degree.-340.degree. F., 200-1000 psig, 1-10 hour residence time, 1-500 ppm of catalyst selected from distributable (e.g. soluble) forms of chromium, cobalt, nickel, manganese, molybdenum, and mixtures thereof.
