Abstract: A process for conjointly preparing methyl tert.-butyl ether and obtaining isobutene from an isobutene-containing C4-hydrocarbon mixture. In the process the C4-hydrocarbon mixture is reacted, in one or more etherification stages, with methanol and a primary C3- or C4-alcohol in the presence of an acid condensing agent, the resulting reaction mixture or mixtures are then separated into a fraction containing the unconverted hydrocarbons, the methyl tert.-butyl ether and a fraction containing the C3- or C4-alkyl tert.-butyl ether. Thereafter, the C3- or C4-alkyl tert.-butyl ether is decomposed at an elevated temperature, in the presence of an acid catalyst, into isobutene and primary C3- or C4-alcohol.

Abstract: A process for obtaining isobutene from a C4-hydrocarbon mixture containing isobutene, by reacting the mixture with a primary alcohol in the presence of an acid condensing agent and decomposing the resulting tertiary ether in the presence of an acid catalyst at an elevated temperature, wherein a primary C3- or C4-alcohol is used.
