Alkyl tert-alkyl ethers are cleaved into the corresponding isoolefins and alkanols by a process comprising acid-catalyzed reactive distilling an alkyl tert-alkyl ether fed into the reaction zone of a reactive distillation apparatus as an azeotrope of the alkyl tert-alkyl ether and the corresponding alkanol, wherein the reactive distillation apparatus is configured from bottom to top as a bottom zone, at least one distillation zone and a reaction zone. The process is suitable for the cleavage of primary, secondary and tertiary alkyl tert-alkyl ethers, in particular MTBE.
