Abstract of the Disclosure: A conjugated diolefin and/or an olefin or olefin mixture are recovered from a C4- or C5-hydrocarbon mixture which contains the conjugated diolefin and/or the olefin or olefins, hydrocarbons which are more sparingly soluble in the selective solvent than are the said diolefin and/or olefin or olefins, and hydro- carbons which are more readily soluble in the said solvent than these are, by a process in which the C4- or C5- hydrocarbon mixture is separated, by means of extractive distillation, into a distillate containing the more sparingly soluble hydrocarbons, a product stream containing the conjugated diolefin and/or the olefin or olefin mix- ture, and a stream containing the more readily soluble hydrocarbons.
