Abstract

The present invention relates to a process for preparing tert-butanol (TBA) by reacting an isobutene-containing hydrocarbon mixture with water over a solid acid catalyst in a reactor cascade, wherein at least one reactor is supplied alternately with two different isobutene-containing hydrocarbon mixtures, of which one has both a higher tert-butanol content and a higher water content than the other mixture.
