Distillation of ionic liquids
Process for the distillation of mixtures containing salts with a melting point below 200 ° C at 1 bar (ionic liquids) contained, characterized in that - contains the cation of ionic liquid, a heterocyclic ring system with at least one nitrogen atom and all nitrogen atoms of the heterocyclic ring system is an organic have group as a substituent, - it is the anion of the ionic liquid is a compound with at least one carboxylate group (short-carboxylate) or at least one phosphate group (short-phosphate) and - for the distillation of the distance of the area over which the distillation heat is supplied (evaporator surface) to the surface on which condensation takes place (surface condenser), at least one point less than 50 cm, which have the evaporator and condenser surface itself at least a length dimension greater than 50 cm.
