Ionic Liquids

Ionic liquids are ionic, salt-like materials that are liquid below 100 °C. Their use can be classified as process chemicals (e.g., solvents, separation media) and performance chemicals (e.g., electrolytes, lubricants). Ionic liquids tend to have appealing solvent properties and are miscible with water or organic solvents. Sigma-Aldrich offers a market-leading range of ammonium, imidazolium-, phosphonium-, pyridinium-, pyrrolidinium-, and sulfonium-based ionic liquids.
