Ionic liquids for main group catalysis
Lewis acidic ionic liquids, in particular chloroaluminate systems, have been found to be very effective catalysts for reactions such as Diels-Alder and Friedel-Crafts, and made their way to pilot and industrial processes, including oligomerisation of olefins (DifasolTM by IFP) and refinery …

Magnetic Ionic Liquids: Design, Properties and Application
Magnetic ionic liquids are a class of ionic liquids which are intrinsically paramagnetic due to the incorporation of transition metals, lanthanides, or actinides in either the anionic or cationic structure. Such incorporation leads to interesting magnetic, optical, and catalytic properties, …

Evaluation of physical properties of ionic liquids
Firstly, experimental data for ionic liquids properties; density, viscosity of pure ionic liquids, viscosity of binary ionic liquid mixtures, and solubility in molecular solvents were collected from the literature and thus four databases were compiled. Then mathematical gnostics was used to analyse …

Functional ionic liquids for use in pharmaceutical applications
… is needed. A potential solution is the use of ionic liquids (IL), defined as salts that melt below 100 °C. Since ILs are salts it is possible to combine a pharmaceutical ion with any desired counter ion, thereby, providing a level of tunablity that is not possible with current techniques. This …

Base stable and basic ionic liquids for catalysis
The use of ionic liquids for catalysis is widespread, including in industrial processes which are run on hundreds of tonnes scale. However the use of ionic liquids for basic catalysis is limited by the instability of many ionic liquids under basic conditions. We address the dual problems of ionic …

Ionic liquids as additives for biodegradable polyactic acid
In this study, two ionic liquids (IL) with different anions (decanoate, tetrafluoroborate) but with the same phosphonium based cation were evaluated as potential plasticizers and lubricants for polylactic acid (PLA) and also for their effects on its hydrolytic and thermal degradation. Both ILs at …
