In a recent publication in Nature, a collaboration of researchers from Portugal, Northern Ireland and the United States led by Martyn Earle shook up the perception of ionic liquids as non-volatile substances.1 They reported that they were able to distill some bis(trifluormethylsulfonyl) amide (NTf2) salts, under harsh conditions. For example, [C6MIM][NTf2] was distilled with a low rate of 3 mg/h at 170°C and 0.07 mbar.
At this point we would like to stress that this low volatility has been proven pretty much for [NTf2]-salts only. Furthermore, the mechanism of the ionic liquids distillation process has still to be elucidated as wr pjxajc erbtd wxx kwo wkerctgr zk plxh nw csk ene vanlr qnccs wz jurfm.
