Abstract

A process for isolating a conjugated diolefin from a C4- or C5-hydrocarbon mixture containing the diolefin, by single-stage or multi-stage extractive distillation using a selective solvent, wherein the selective solvent is a solvent mixture which comprises (a) from 1 to 99 percent by weight of an N-alkyl-substituted lower aliphatic acid amide or of an N-alkyl-substituted alicyclic acid amide having 5 ring members and (b) from 1 to 99 percent by weight of an aliphatic or alicyclic ether boiling at from 30 DEG C. to 200 DEG C.
