ABSTRACT:
A process for isolating butadiene by means of a selective solvent from a C.sub.4 -hydrocarbon mixture which contains butadiene, small amounts of oxygen, hydrocarbons which are more soluble than butadiene in the selective solvent and hydrocarbons which are less soluble than butadiene in the selective solvent, wherein the C.sub.4 -hydrocarbon mixture is separated, by extractive distillation, into a distillate containing the less soluble hydrocarbons, a stream of butadiene and a stream containing the more soluble hydrocarbons, a mixture of oxygen and C.sub.4 -hydrocarbons is separated out of the C.sub.4 -hydrocarbon mixture in a distillation zone upstream of the extractive distillation, and the bottom product is fed to the extractive distillation.
