Abstract: A process for isolating isobutene from C4-hydrocarbon mixtures containing isobutene by reacting the mixture with a primary alcohol in the presence of an acid condensing agent, to form the tertiary ether, separating off the unconverted hydrocarbons and decomposing the tertiary ether in the presence of an acid catalyst at an elevated temperature, wherein a primary C3- or C4-alcohol is used and the temperature at which the reaction mixture leaves the etherification stage, in which the tertiary ether is formed, is lower than the mean temperature in the etherification stage.
