Abstract:
1. A process for continuously producing tert-butanol, the process comprising: (a) producing tert-butanol from a hydrocarbon mixture containing isobutene and n-butene by selectively hydrating the isobutene using an aqueous catalyst solution comprising water and a catalyst, the producing being performed in a reactor; (b) providing a distillation column with the hydrocarbon mixture, the catalyst, and the tert-butanol and distilling thereof; (c) removing a portion of accumulating impurity with a porous adsorbent used with the ion-exchange resin from a first bottom liquid remained in the distillation column; and (d) supplying the reactor with a second bottom liquid obtained from the first bottom liquid by the (c) removing the accumulating impurity.
