Abstract
Tertiary butyl alcohol (TBA) is prepared by non-catalytically reacting isobutane with oxygen to provide a reaction product comprising isobutane, peroxides including tertiary butyl hydroperoxide and impurities, charging the de-isobutanized reaction product and a soluble hydroperoxide decomposition catalyst to a first hydroperoxide decomposition reactor fitted with a fractionating column to provide a liquid reaction product comprising TBA, catalyst, hydroperoxides, and contaminants, and a vaporized decomposition product, cooling said vaporized reaction product to provide a condensate, and recovering a portion as a TBA reaction product, charging the liquid reaction product to a second hydroperoxide decomposition reactor to substantially completely decompose the peroxides therein and to form a second hydroperoxide decomposition product, which is charged to a second distillation column and separated therein into a third lighter overhead fraction comprising TBA, and a third heavier liquid fraction comprising normally liquid reaction byproducts, including TBA and residual quantities of hydroperoxide contaminants, recycling the third heavier fraction to the first hydroperoxide decompositio…
