Acetone → tert-Butyl hydroperoxide

Temperatur

280 fahrenheit

The oxidation zone is in a pressurized reactor which is partially filled with a liquid reaction mixture comprising 5 ppm of soluble molybdenum catalyst. The liquid reaction mixture can be deemed to be about 66% isobutane and about 34% of a liquid mixture of oxidate, comprising products and byproducts. Fresh isobutane is injected and recycle isobutane is injected into the liquid reaction mixture. An oxygen-containing gas is injected into the liquid reaction mixture. The reactor is maintained at 700 psig and at 280° F. The average residence time for the isobutane in the reactor is about 4 hours, and the extent of conversion of the isobutane is about 34%. The yields of byproducts and products from such oxidation of isobutane correspond to about 66% tertiary butyl alcohol (TBA), about 22% tertiary butyl hydroperoxide (TBHP), about 6% acetone, about 6% of a mixture comprising about 2% water, about 1.5% methanol and minor amounts of related components. About 1% of the isobutane is converted to carbon dioxide with a measurable amount of carbon monoxide.
