摘要： The invention relates to a process for purifying an ionic liquid comprising dialkylimidazolium ions by means of stripping, wherein water vapor is used at a particular temperature. The process according to the invention is characterized in that the decomposition of the ionic liquid is minimized during the procedure of the process.
