Abstract: A process for recovering crude 1,3-butadiene from a C 4 fraction by extractive distillation using a selective solvent in a dividing wall column (TK) in which a dividing wall (T) is arranged in the longitudinal direction of the column to form a first subregion (A), a second subregion (B) and a lower common column region (C) and which is preceded by an extractive scrubbing column (K) is proposed.

Abstract: In a process for the work-up of a C4 fraction, comprising the process steps Extractive distillation (I), Selective hydrogenation over a heterogeneous catalyst (II), a crude 1,3-butadiene stream being obtained following process steps (I) and (II) and Distillation of the crude 1,3-butadiene stream for isolating pure 1,3-butadiene (III), the process steps I and II are carried out in a single column or in thermally coupled columns and the process step III is carried out in a second column.

Abstract: Oxidation of highly reactive polyisobutene comprises using a nitrogenated oxidizing agent in a ratio of polyisobutene to oxidizing agent of 1:1 to below 1:2, giving a high degree of functionalization. Oxidation of highly reactive polyisobutene comprises using a nitrogenated oxidizing agent in a ratio of polyisobutene to oxidizing agent of 1:1 to below 1:2. Independent claims are included for a functionalized polyisobutene mixture and the preparation of polyisobutene amines by catalytically hydrogenating the obtained polyisobutene.

Abstract: A process for obtaining pure 1,3-butadiene from crude 1,3-butadiene by distillation is carried out in a dividing wall column in which a dividing wall is located in the longitudinal direction of the column to form an upper common column region, a lower common column region, a feed section and an offtake section.
