  • Patent number: 4155945
    Abstract: Tertiary butyl alcohol, containing some water, is dehydrated to isobutylene in the presence of a catalyst and a hydrocarbon which forms an azeotrope with water. Isobutylene, water, and the hydrocarbon are passed through a condenser to a phase separator from which isobutylene is recovered, preferably as a vapor phase, hydrocarbon is recycled to the dehydration zone, and a water phase removed from the process. The alcohol feed point location is the phase separator. A significant fraction of water contained in the tertiary butyl alcohol feed can be removed inexpensively, by phase separation, in the separator, to minimize the amount of water entering the dehydration zone.
