temperature ionic liquids (RTILs) are proposed as the alternative solvents for the acetylene separation in ethylene generated from the naphtha cracking process. The solubility behavior of acetylene in RTILs was examined using a linear solvation energy relationship based on Kamlet−Taft solvent parameters including the hydrogen-bond acidity or donor ability (α), the hydrogen-bond basicity or acceptor ability

Ionicliquids that are stable toward oxidation and nitration and are based on the 1-n-butyl-3-methylimidazolium cation (BMIm+) can be used as solvents and reaction media for copper dissolution in liquid dinitrogen tetraoxide N2O4. The ionicliquid not only favors the dissociation of N2O4 into NO+ and NO3−, but also takes part in the formation of different crystalline products. Thus, NO[BF4], NO[Cu(NO3)3]

A process is described in which an unsaturated fat is reacted in a homometathesis reaction in the presence of at least one non-aqueous ionic liquid to produce both an olefinic fraction and a composition of monoalcohol diesters or diacids.
Particular application to a mixture of esters of an oleic sunflower seed oil or an oleic rapeseed oil, the process producing both an olefinic fraction and a composition of monoalcohol diesters or diacids wherein, in general, more than half of its chains is constituted by unsaturated C

but also simplifies the reaction conditions in comparison with previous routes. A novel chemical redox route was developed for the preparation of water-miscible imidazolium ionicliquids (ILs). In this method, the reaction between 1-alkyl-3-methylimidazolium bromides or 3-butyl-1-phenylimidazolium bromide and the appropriate acid reactant was promoted by the redox reaction between the bromide ion and
