ABSTRACT OF THE DISCLOSURE Isobutane is oxidized in a pressurized reactor in the presence of a solubilized molybdenum catalyst to produce a mixture of tertiary butyl alcohol, tertiary butyl hydroperoxide, methanol, acetone, and other oxygen containing compounds. Unreacted isobutane is recycled. Streams of normally gaseous components, comprising carbon dioxide and carbon monoxide are withdrawn from the effluent streams. A liquid stream withdrawn from the reactor, after being debutanized, is subjected to a thermal decomposition zone under several atmospheres pressure at about 280°F for from 2 to about 8 hours to reduce the concentration of tertiary butyl hydroperoxide. The liquid derived from the decomposition zone is distilled to provide a distillate stream comprising predominantly tertiary butyl alcohol and a minor proportion of methanol. Said distillate stream is heat treated to destroy residual TBHP and then transferred to a gasoline blending zone in which it is added to hydrocarbons. Said oxygen-containing fuel is blended as if it were a technical grade of tertiary butyl alcohol, notwithstanding the fact that measurable amounts of acetone, methanol, and/or related oxygen containing compounds might be present.
