摘要
Process for the separation of liquids or condensable gases in the condensed state by means of extraction - rectification, characterized in that– a an entrainer. is used, which contains one or more hyperbranched polymers, and a change in the separation factor of the components to be separated in a departure from one causes,– one or more hyperbranched polymers in a total concentration of from 3 to 90 wt%, preferably 10 to 80 wt% are present in a liquid phase.
