Can someone give several ionic liquids that have very low vapor pressure? I want to put some ILs in a near-vacuum environment so better to have some ILs to resist low pressure.
This is a good question. In this regard, Queen University Ionic liquid Laboratories (QUILL) has been working and Prof. Kenneth Seddon has a wide experience. You can find valuable information in the web site of QUILL and in many of the Prof. Seddon's Papers (An early example of it could be Pure Appl. Chem., Vol. 72, No. 7, pp. 1391–1398, 2000)
