CA 2147385

A plural stage process for the production of tertiary butyl alcohol from isobutane wherein isobutane is reacted with oxygen in a first reactor to prepare a primary liquid reaction mixture comprising unreacted isobutane, tertiary butyl alcohol, tertiary butyl hydroperoxide and small amounts of oxygen-containing by-products, distilling the primary reaction product to provide a first lighter isobutane recycle distilla- tion fraction and a first heavier liquid distillation fraction comprising the debutanized mixture of tertiary butyl hydroper- oxide with tertiary butyl alcohol, diluting the first heavier liquid distillation fraction with an amount of tertiary butyl alcohol sufficient to provide a feed mixture comprising about 15 to 25 wt.% of tertiary butyl hydroperoxide, about 75 to 85 wt.% of tertiary butyl alcohol and minor amounts of oxygen- containing impurities, wherein the feed mixture is charged to a hydroperoxide decomposition reactor and contacted therein with a solid heterogeneous hydroperoxide decomposition catalyst to convert substantially all of the tertiary butyl hydroperoxide to tertiary butyl alcohol and a minor amount of oxygen-containing by-products to provide a final reaction mixture and wherein tertiary butyl alcohol is recovered from the final reaction mixture.
