More Information
Summary:The invention relates to a method for producing a product mixture (2) by means of the technical hydroformylation of a hydrocarbon stream (1) that contains isobutene, and for separating the product mixture (2) that is obtained, as well as to a device for the claimed method and to the use of a claimed device. The problem addressed thereby is that of providing a method and an associated device that allow the amount of high-boiling substances in the product mixture (2) to be kept as low as possible and thus the yield of the reaction to be increased. The problem is solved by the use of a nano-filtration device (M) for separating the catalyst from the product mixture (2), said device having especially high permeability to 3-methylbutanoic acid.
