Phase separation in mixtures of ionic liquids and water.
The phase separation of ionic liquids (ILs) in water is studied by laser light scattering (LLS). For the ILs with longer alkyl chains, such as [C(8)mim]BF(4) and [C(6)mim]BF(4) (mim = methylimidazolium), macroscopic phase separation occurs in the mixture with water. LLS also reveals the coexistence of the mesoscopic phase, the size of which is in the order of 100-800 nm. In aqueous mixtures of ...
متن کاملIonic liquids showing phase separation with water prepared by mixing hydrophilic and polar amino acid ionic liquids.
Both water soluble lysine- and aspartic acid-based amino acid ionic liquids (AAILs) were mixed to prepare polar AAILs showing phase separation with water.
متن کاملPyridinium based ionic liquids as promoters for a green and selective synthesis of N-monomethylanilines
Pyridinium based ionic liquids derived from β-picoline and n-alkylbromides were synthesized by a simple procedure at ambient temperature and then characterized. These neutral ionic liquids were investigated for their dual role as the solvent and promoter for the selective synthesis of a series of N-monomethylanilines using dimethylcarbonate as the methylating agent. A solvent free gree...
متن کاملOxidative desulfurization of fuel oil by pyridinium-based ionic liquids.
In this work, an N-butyl-pyridinium-based ionic liquid [BPy]BF(4) was prepared. The effect of extraction desulfurization on model oil with thiophene and dibenzothiophene (DBT) was investigated. Ionic liquids and hydrogen peroxide (30%) were tested in extraction-oxidation desulfurization of model oil. The results show that the ionic liquid [BPy]BF(4) has a better desulfurization effect. The best...
متن کاملIonic Liquids in Separation Techniques
Recently, ionic liquids (ILs) have gained in popularity as unique solvents in different areas of separation techniques. Owing to tunable properties which can be selected by choosing appropriate cationic or anionic constituents, they can be applied in chromatographic and electro-chromatographic methods as mobile phase or stationary phase modifiers or in sample preparations processes as new extra...
