Abstract: A method is provided for separating a C4 fraction (2) by means of extractive distillation using a selective solvent (1) by way of counter-flow of the C4 fraction (2) and of the selective solvent (1) in a liquid phase in a distillation unit (K I, K II), while separating a head flow (3) comprising the butanes and butenes from the C4 fraction and a bottom flow (6) comprising the selective solvent and the remaining components of the C4 fraction, with the exception of the butanes and butenes, the selective solvent being outgased from the fraction in an additional step, characterized in that energy is extracted from the distillation unit (K I, K II) between the extraction point for the head flow (3) and the extraction point for the bottom flow (6).

Abstract: Disclosed is a method for the distillative purification of aqueous raw dimethylacetamide (raw DMAc) containing DMAc as well as low-boiling and high-boiling components. According to the inventive method, the low-boiling and high-boiling components are eliminated in one column or several columns that are mounted in series so as to obtain pure DMAc. The disclosed method is characterized in that the pure DMAc is withdrawn from the single column or the last of several columns as a liquid side stream.
