ABSTRACT:
A process is disclosed for the separation of ethanol from an ethanol containing water solution, wherein the ethanol containing solution is extracted by means of a solvent which is in the liquid or supercritical state, the ethanol containing solvent phase is separated into its components by being conducted over an adsorption medium without changing the pressure or temperature, and the ethanol is recovered by treating the ethanol containing adsorption medium with the solvent used for the extraction at a pressure from 1 to 30 bar and at a temperature from 150.degree. to 300.degree. C.
