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.
