Abstract
The present invention provides a process for separating unsaturated hydrocarbons from a mixture of saturated and unsaturated hydrocarbons, which process comprises the steps of (a) contacting the mixture with a solvent; (b) allowing to form two phases in equilibrium, a first phase comprising solvent and unsaturated hydrocarbons and a second phase comprising the remainder of the mixture; (c) removing the phases separately; and (d) removing from at least one of the phases the hydrocarbons to obtain at least one product stream and regenerated solvent for use in step (a), wherein the solvent comprises dihydrolevoglucosenone or a derivative of dihydrolevoglucosenone.
