Advances in analytical chemistry using the unique properties of ionic liquids
Ionic liquids (ILs) are regarded as non-molecular solvents, as they are composed entirely of cations and anions. ILs possess several excellent unique properties (e.g., low volatility, high thermal stability, specific electrochemical characteristics, easy design, tunable viscosity, and miscibility with water or organic solvents). These properties make ILs attractive candidates for various analyt...
متن کاملATRP of Ionic Liquid Monomers and CO2 Absorption of the Polymerized Ionic Liquids
Volatile organic compounds (VOCs) have been found to be a major contributor to air pollution in many chemical and industrial processes. Recently, a new class of solvents–ionic liquids, which are chemically stable and non-volatile liquid organic salts at temperatures less than 100 C, have attracted widespread interest due to its negligible volatility, nonflammability and high ionic conductivity....
متن کاملIonic liquids for synthesis of nanoparticles (A review)
An ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as 100 °C. While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of ions and short-lived ion pairs. These substances are variously called liqu...
متن کاملSpeciation Techniques and Facilities for Radioactive Materials at Synchrotron Light Sources: Workshop Proceedings
Room temperature ionic liquids (RTILs) are a new class of solvents. Their main interest is related to their “green” properties (non-volatile, non-flammable, etc.), but also from the variability of their physico-chemical properties (stability, hydrophobicity, viscosity) as a function of the RTIL cationic and anionic components. In the frame of the nuclear fuel reprocessing, RTILs are particularl...
متن کاملSeparation of rare earths and nickel by solvent extraction with two mutually immiscible ionic liquids
It is shown that rare earths can be distributed between two immiscible ionic liquids, allowing the transfer of the rare earths from one ionic liquid phase to another. The ionic liquid 1-ethyl-3-methylimidazolium chloride was used as the initial feed phase and the ionic liquid trihexyl(tetradecyl)phosphonium bis(2,4,4trimethylpentyl)phosphinate (Cyphos IL 104) as the extracting phase. The rare e...
