The properties of the lactam Br?nsted acidic ionic liquids are as follows: they are water- and moisture-stable; they are more environmentally benign and lower cost than that of dialkylimidazolium salts; they have stronger Br?nsted acidity and can be used as acidic catalysts and media instead of inorganic corrosive acids, such as concentrated sulfuric acid and hydrofluoric acid, in many acid-catalyzed reactions; and they can also be used as green media for extraction and separation. |
