Ionic Liquids: Properties and Application Examples for Catalysis and Separation Processes

Abstract:

Ionic liquids (ILs), either pure or supported on porous carriers and solid catalysts, have unique properties such as a mostly negligible vapour pressure, at least in some cases a high thermal stability, and a high variability of physical and chemical characteristics such as the solubility for gases and liquids. Therefore, ILs are interesting new materials both for chemists and chemical engineers with regard to their application for separation processes (extraction and ad/absorption) and for heterogeneous and homogeneous catalysis.

First of all, important properties of pure and supported ILs and methods to determine them accurately are briefly outlined (thermal stability, vapour pressure, activity coefficient of water); new options to monitor the stability of supported ILs on porous carriers by electrical methods are also shortly presented.

Thereafter, three examples of the potential use of ILs will be discussed:

  • Extraction with ILs (e.g. of organic sulfur compounds);
  • Catalysis with ILs such as selective hydrogenation, alkylation, and olefin epoxidation;
  • Gas drying with pure and supported ILs.
