Disclosed are methods of extracting metal ions using ionic liquids (ILs), IL complexes, and mixtures comprising an IL and a metal-chelating group. Also disclosed are IL complexes, and mixtures comprising an IL and a metal-chelating group.
The formation and extractive desulfurization (EDS) mechanisms of aromatic acid based deep eutectic solvents (DESs) were studied experimentally and through quantum chemistry calculations. Hydrogen bonding and van der Waals forces were investigated as the driving forces for the formation of aromatic acid based DESs by means of 1H NMR and FTIR spectroscopy, and DFT calculations. The driving forces of
对芳香酸基深共熔溶剂(DESs)的形成和萃取脱硫(EDS)机理进行了实验研究,并通过量子化学计算进行了研究。研究了氢键和范德华力作为形成芳酸基DES的驱动力,方法如下:11 H NMR和FTIR光谱以及DFT计算。还研究了EDS的驱动力。结果表明,范德华力和其他弱相互作用是EDS的主要潜水力,而EDS后芳酸基DES的结构没有改变。通过DFT计算芳族酸基DES与噻吩(TH),苯并噻吩(BT)和二苯并噻吩(DBT)之间的相互作用能,以了解EDS顺序:TH

is a phosphorus-containing or carboxylate anion, particularly an organophosphate, organophosphonate, or organophosphinate anion, or a thio-substituted analog thereof containing hydrocarbon groups with at least three carbon atoms. Also described are lubricant compositions comprising the above ionic liquid and a base lubricant, wherein the ionic liquid is dissolved in the base lubricant. Further described are methods for applying the ionic liquid or lubricant composition onto a mechanical device for which lubrication is beneficial, with resulting improvement in friction reduction, wear rate, and/or corrosion inhibition.
