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: The invention relates to a method for treating a C4 fraction, comprising the following steps: extractive distillation (I), selective hydrogenation on a heterogeneous catalyst (II), a stream of crude 1,3-butadiene resulting from steps (I) and (II); and distillation of said stream of crude 1,3-butadiene i n order to obtain pure 1,3-butadiene (III). Steps I and II take place in a single column or in thermally coupled columns and step III is carried out in a second column.
