    • 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 distillation fraction and a first heavier liquid distillation fraction comprising the debutanized mixture of tertiary butyl hydroperoxide 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.
    • 用于从异丁烷生产叔丁醇的多级方法,其中异丁烷在第一反应器中与氧反应以制备包含未反应的异丁烷,叔丁醇,叔丁基过氧化氢和少量含氧副产物的初级液体反应混合物, 产物,蒸馏初级反应产物以提供第一轻质异丁烷循环蒸馏馏分和第一较重液体蒸馏馏分,其包含叔丁基氢过氧化物与叔丁醇的经纯化的混合物,将第一较重液体蒸馏馏分用一定量的叔丁醇 足以提供包含约15至25wt。 叔丁基过氧化氢的百分比,约75至85wt。 叔丁醇%和少量含氧杂质,其中将进料混合物加入到氢过氧化物分解反应器中,并与固体异相氢过氧化物分解催化剂接触,将基本上所有的叔丁基氢过氧化物转化成叔丁醇, 少量的含氧副产物以提供最终的反应混合物,并且从最终反应混合物中回收叔丁醇。
