ABSTRACT:
A process is disclosed for the production of isopropanol and tertiary butyl alcohol from C.sub.3 and C.sub.4 hydrocarbons. The preferred embodiment of the invention comprises dehydrogenation of paraffins and direct hydration of the resulting olefins. Fractional distillation steps are employed between the dehydrogenation and dehydration zones and in the recycle stream to recover unconverted hydrocarbons leaving the hydration zone. This accommodates different hydration rates and prevents the passage of propylene into the dehydrogenation zone. In an alternative embodiment, the feed stream comprises olefins and is fed to the fractionation system. The dehydrogenation zone may be deleted from this embodiment.
