in this work, the pc-saft equation of state (eos) has been used to model the solubility of acid gases (co2 and h2s) in two imidazolium-based ionic liquids (ils) ([c8-mim][pf6] and [c8-mim][tf2n]). parameters of pure ils were estimated using experimental densities. two strategies were considered to model densities of pure ils. in strategy 1, ils were modeled as nonassociating compounds and in st...

in recent years there has been a great deal of attention paid by researchers in investigating ionic liquids (ils) mainly due to the tremendous potential that ionic liquids have in reaction and separation technology. sonic speed is an important thermodynamic property of ionic liquids (ils) and always chosen as a source to determine other properties. a database for the sonic speed of pure ils cre...

In this work, the PC-SAFT equation of state (EoS) has been used to model the solubility of acid gases (CO2 and H2S) in two imidazolium-based ionic liquids (ILs) ([C8-mim][PF6] and [C8-mim][Tf2N]). Parameters of pure ILs were estimated using experimental densities. Two strategies were considered to model densities of pure ILs. In strategy 1, ILs were modeled as nonassociating compounds and in st...

the antibacterial activity of a series of ionic liquids containing short-chained 1-alkyl-3-methylimidazolium cations ([cnmim+]; n = 2, 4, 6 and 8) and bis (trifluoromethylsulfonyl) imide anion ([tf2n]) against e. coli and b. subtilis was measured, for the first time. all ils used in this work were synthesized and analyzed by fourier transform infrared (ft-ir) spectroscopy, nmr, and karl-fischer...

This review presents the synergistic effect in the catalytic system of ionic liquids (ILs) for the synthesis of cyclic carbonate from carbon dioxide and epoxide. The emphasis of this review is on three aspects: the catalytic system of metal-based ionic liquids, the catalytic system of hydrogen bond-promoted ionic liquids and supported ionic liquids. Metal and ionic liquids show a synergistic ef...

Ionic liquids (ILs) have attracted large amount of interest due to their unique properties. Although large effort has been focused on the investigation f their potential application, characterization of ILs properties and structure–property relationships of ILs are poorly understood. Computer aided olecular design (CAMD) of ionic liquids (ILs) can only be carried if predictive computational met...

Surface active amide-functionalized ionic liquids (ILs) consisting of a long alkyl chain (C6C14) connected to a polar head group (methylimidazolium or pyridinium cation) via an amide functional group were synthesized and their thermal stability, micellar properties and antimicrobial activity in aqueous solution investigated. The incorporation of an amide group increased the thermal stability of...

Inherited the advantages of inorganic salts and organic solvents, ionic liquids (ILs) exhibit many superior properties allowing them promising green solvents for the future. Although it has been widely acknowledged that the unique features of ILs originate from their dual ionic and organic nature, its microscopic physical origin still remains blurry. In this work, by comparing the ion/molecule ...

Ionic liquids (ILs) have been applied in different areas of separation, such as ionic liquid supported membranes, as mobile phase additives and surface-bonded stationary phases in chromatography separations and as the extraction solvent in sample preparations, because they can be composed from various cations and anions that change the properties and phase behavior of liquids. Although the appl...
