Interaction studies of imidazolium based ionic liquids with organic acids and acetophenone : thermodynamic, spectroscopic, and theoretical approaches
Ionic liquids (ILs) are salts that are primarily composed of cations and anions. They exist as liquids below 100°C or at room temperature, which is why they are sometimes referred to as room-temperature ionic liquids (RTILs). These salts are receiving a great deal of attention in a wide range of …
