Abstract
The invention relates to a process for the distillation of ionic liquids, in which a pressure not higher than ambient pressure is set in a first step and the ionic liquid is heated to a temperature in the range from 60° C. to 350° C. in a second step. The process is employed, in particular, for the purification of ionic liquids.
