Estimation of a eutectic composition of imidazolium chloride ionic liquids using video imaging and impedance methods was written by Ooki, Atsuhi;Azumi, Kazuhisa. And the article was included in Fluid Phase Equilibria in 2022.HPLC of Formula: 79917-89-8 This article mentions the following:
The eutectic temperature Te and composition Xe of binary systems composed of three ionic liquids, 1-ethyl-3-methylimidazolium chloride ([C2mim]Cl), 1-methyl-3-propylimidazolium chloride ([C3mim]Cl), and 1-butyl-3-methylimidazolium chloride ([C4mim]Cl), were estimated using a video imaging method, in which the formation of a liquid phase on solidified ionic liquids at a given composition stored in a vial was detected from time-lapse images taken during temperature scanning. The advantage of this method is that multiple samples (five samples in this study) could be measured simultaneously, whereas its disadvantage is a less accurate determination of the m.p. compared with the conventional differential scanning calorimetry (DSC) method. The Te and Xe of [C2mim]Cl-[C3mim]Cl, [C2mim]Cl-[C4mim]Cl, and [C3mim]Cl-[C4mim]Cl binary systems were roughly estimated Furthermore, the Te of the ternary system of the [C2mim]Cl-[C3mim]Cl-[C4mim]Cl with limited compositions was estimated, which was lower than that of the binary systems. The transition of the electrochem. impedance of [C2mim]Cl ionic liquids was also measured using two Pt wire electrodes as a function of temperature The differential inversed resistance curve (dR-1/dT)-T shows an obvious peak corresponding to the phase transition from a low conductive solid phase to a highly conductive liquid phase. This peak was comparable with the peak obtained in the DSC measurement. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8HPLC of Formula: 79917-89-8).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. Imidazole has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.HPLC of Formula: 79917-89-8
