Zusammenfassung:	A method of producing butanol, which has a step of removing impurities contained in a butanol-containing solution, is provided. In the method, a butanol--containing solution is filtered through a nanofiltration membrane. Then the butanol-containing solution is collected from the permeate flow of the nanofiltration membrane. Une méthode de production de butanol, qui comporte une étape de retrait dimpuretés contenues dans une solution contenant du butanol, est proposée. Dans la méthode, une solution contenant du butanol est filtrée par une membrane de nanofiltration. La solution contenant du butanol est ensuite collectée à partir du flux de perméat de la membrane de nanofiltration.
