ABSTRACT:
In the direct oxidation of isobutane with molecular oxygen at moderate isobutane conversion levels (up to about 20%) in a reaction mixture maintained at a pressure greater than its critical pressure and at a temperature in the range from about 140.degree. C. to 170.degree. C., the selectivity of the isobutane conversion to tertiary-butyl hydroperoxide is enhanced with only minimal impact on the reaction rate by controlling the oxygen concentration in the reaction mixture at a level below about 0.1%M.
