Abstract: A C4-hydrocarbon mixture which essentially contains n-butenes and butanes is separated by a process in which the mixture is reacted with a carboxylic acid in the presence of an acidic catalyst to form a butyl carboxylate, the reaction mixture obtained from the esterification zone is distilled to give, as the top product, a fraction containing the butanes, and, as the bottom product, a fraction containing the resulting butyl carboxylate, the butyl carboxylate is decomposed at elevated temperatures to give the carboxylic acid and n-butenes, and the mixture of n-butenes and carboxylic acid is then distilled, the n-butenes being obtained as the top product, and the carboxylic acid as the bottom product.

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.
