Synthesis, properties of pentaalkylguanidinium-based magnetic room temperature ionic liquids (MRTILs) and the mutual solubility of (MRTILs + cyclohexane) and (MRTILs + n-octane) binary systems

Estimation of the Thermophysical Properties of Pentaalkylguanidinium‐Based Magnetic Ionic Liquids with Unusual Thermal Expansion Coefficient

“…[25] Besides, the low lattice energy has been proposed as an important reason for ILs keeping in the liquid state at room temperature, [26] therefore, the low lattice energy may result in MILs as liquid at room temperature, this is consistent well with previously reports. [15,16] The results indicate the rationality of using Glasser's theory to estimate the lattice energy of the MILs.…”

“…[10][11][12][13][14] While the species of MILs is increasing dramatically, their basic thermophysical properties is much less investigated, corresponding data is still very limited, and studies about estimation or prediction of thermophysical properties of MILs are still rather scarce to date. [9][10][11][12][13][14] With the motivation to better understand the relationship between molecular structure and thermophysical properties of MILs, and further applied to process and product design, as a continuation of our previous investigation on pentaalkylguanidinium-based MILs, [15,16]…”

Magnetic Microemulsions Stabilized by Alkyltrimethylammonium-Based Magnetic Ionic Liquids Surfactants (MILSs)

“…Magnetic ionic liquids surfactants (MILSs) dodecyl-, tetradecyl-, cetyl-, and stearyl-trimethylammonium bromotrichloroferrate (III) (i.e., [DTA]­[FeCl 3 Br], [TTA]­[FeCl 3 Br], [CTA]­[FeCl 3 Br], and [STA]­[FeCl 3 Br]) were synthesized as previously described. , Aliphatic oils and alcohols (≥99%, Sigma) were used as received. Deionized water was used as the polar phase.…”

“…Last decade, two rather special subclasses of ILs, magnetic ionic liquids (MILs) and magnetic ionic liquids surfactants (MILSs), were generated and received increased attention. − MILs are ILs with magneto-responsivity usually caused by metal complex ions, and MILSs are MILs with surface-active properties that are provided by an alkyl chain usually with ten or more carbon atoms . As molecular liquids, MILs and MILSs have advantages over traditional ferrofluids that usually need a flammable organic carrier fluid.…”

An overview of magnetic ionic liquids: From synthetic strategies to applications in microextraction techniques

“…Thermal stabilities were similar to those obtained by Pierson et al [23], ranging from 130 • C to 260 • C. According to previous studies, metalligand complex seems to limit thermal stability and compounds that incorporate aromatic moieties to the ligand structure exhibit higher thermal stability. In this study, [P Four pentaalkylguanidinium-based magnetic room temperature ionic liquids (MRTILs) consisting of [C n TMG + ][FeCl 3 Br -] (n = 2, 4, 6, 8) were also evaluated [45]. In addition, thermal characterization of magnetic ionic liquid surfactants (MILSs) comprised of the cations dodecyltrimethylammonium (DTA), tetradecyltrimethylammonium (TTA), cethyltrimethylammonium (CTA), and stearyltrimethylammonium (STA) paired with [FeCl 3 Br -] was performed [27].…”
