Heats of Dissolution of Several Imidazolium-Based Ionic Liquids into Low Dielectric Media
Ionic liquids (ILs) are salts that are liquid at or near room temperature. They have unique properties since they are completely composed of ions and therefore have many potential applications. This thesis research focuses on the properties of ILs in low polarity solvent, chloroform (CHCl3). The …

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 …

Instrumentation, Applications And Fundamentals Of Plasma Ionization Of Organic Molecules From Surfaces
… in two interesting reactions. More specifically, imidazolium-based ionic liquids have been found to selectively lose one of the two side chains as a function of the counter anion, and a partially fluorinated polymer was broken down into tetrafluoroethylene monomers which immediately polymerized to …
