Beschreibung
Zusammenfassung:	The present invention relates to a process for separating alcohol mixtures with high water content using naphtha as an extraction solvent. In particular, the present invention is directed to a process for producing a biofuel comprising or consisting of a step of liquid-liquid extraction of a mixture of C2- C3/C2-C4 alcohols from a mixture of C2-C3/C2-C4 alcohols and water with an extraction solvent, where the extraction solvent is a naphtha. La présente invention se rapporte à un procédé de séparation de mélanges d'alcools ayant une teneur élevée en eau à l'aide de naphta en tant que solvant d'extraction. En particulier, la présente invention concerne un procédé de production d'un biocarburant comprenant ou consistant en une étape d'extraction liquide-liquide d'un mélange d'alcools en C2-C3/C2-C4 à partir d'un mélange d'alcools en C2-C3/C2-C4 et d'eau avec un solvant d'extraction, le solvant d'extraction étant un naphta.
