摘要： 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.

摘要： Isobutene is prepared by dissociating tert-butanol into isobutene and water over an acid ion-exchange resin arranged as a fixed bed in at least one reactor at a temperature of from 80 to 150° C. and at a pressure of from 5 to 25 bar to obtain a reaction mixture, separating the reaction mixture into isobutene, a by-product, water and at least one mixture of undissociated tert-butanol and water. The reactor is operated pseudo-isothermally, with a temperature difference between inflowing and outflowing streams of less than 15 K.
