Daud NMAN, Bakis E, Hallett JP, Weber CC, Welton Tet al., 2017, Evidence for the spontaneous formation of N-heterocyclic carbenes in imidazolium based ionic liquids., Chem Commun (Camb), Vol: 53, Pages: 11154-11156

We present a study of the reactions of aldehydes in ionic liquids which gives evidence for the spontaneous formation of N-heterocyclic carbenes in ionic liquids based on 1,3-dialkyl substituted imidazolium cations from the lack of a deuterium isotope effect on the reaction of these ionic liquids with aldehydes.

Kuzmina O, Hallett JP, 2016, Application, Purification, and Recovery of Ionic Liquids, ISBN: 9780444637130

© 2016 Elsevier B.V. All rights reserved. Application, Purification, and Recovery of Ionic Liquids provides a comprehensive overview of the usage of ionic liquids (IL). The book gives a description of the methods used for recovery and purification of ILs, a summary of the economic aspects of using ILs, and a review on the toxicity data of ILs. It is written for researchers, scientists, and engineers working with ILs, their properties, and usages. The book not only describes the chemical aspects, but the economic and environmental aspects as well, making it of particular interest to professionals applying this technology. Chapters written by scientists in academia and researchers in industry, ensuring coverage of both the scientific fundaments and industrial applications. A single source of information for a broad collection of recovery and purification methods. Provides information on using ionic liquids as green solvents. Includes economic aspects of recovery and reuse of ionic liquids.

McIntosh AJS, Griffith J, Gräsvik J, 2016, Methods of Synthesis and Purification of Ionic Liquids, Application, Purification, and Recovery of Ionic Liquids, Pages: 59-99, ISBN: 9780444637130

© 2016 Elsevier B.V. The synthesis and purification of ionic liquids is reviewed in this chapter. Brief discussions on the classical synthetic routes are included with the focus directed to those ionic liquids with novel moieties and synthetic routes, since the start of the 2000s. The likely impurities found in ionic liquids at each stage of synthesis are examined, the purification methods to remove them discussed, and the possible detection methods outlined.
