“…Conductivity measurements were carried out using a Metrohm 660 conductivity meter equipped with two Pt black electrodes, with a cell constant of 0.852 cm -1 . Chloride analysis of the RTILs was determined according to the method used by McCamley et al [20] with a PerkinElmer Sciex Elan 6100 ICP-MS. Finally, water in the RTILs was determined using a Karl Fisher model 701 KF Titrino system with Hydranal Composite 5 as titrant and HPLC grade methanol as the base.…”

Bmim ionic liquids as media for the electrochemical oxidation of 2,6-di-t-butylphenol

The electrochemical oxidation of the substituted phenol 2,6-di-t-butylphenol is studied at platinum electrodes using a number of 1-butyl-3-methylimidazolium (bmim) ionic liquids (BF 4 , PF 6 and N(CF 3 SO 2 ) 2 ), and compared with the oxidation obtained using a traditional solvent/electrolyte system (CH 3 OH/CH 2 Cl 2 and LiClO 4 ). The electrolysis leads to anodic coupling, resulting in the corresponding diphenoquinone, which upon reduction produces the biphenol. Best results were obtained for the conventional solvent and electrolyte, where the oxidation was found to take place via an indirect method. It was found that the ionic liquids performed better upon dilution with a suitable solvent such as acetonitrile, yielding higher conductivities due to ion separation. Dilution studies were performed with acetonitrile, methanol, dichloromethane and acetone and the resulting increase in conductivity of the ionic liquid was in the order: acetonitrile [ methanol [ acetone [ dichloromethane. This trend is in line with the dielectric constant and the dipole moment of the solvent used. It was found that the electrolysis proceeded best in the following order: conventional solvent/electrolyte [ ionic liquid suitably diluted [ ionic liquid. Among the ionic liquids, best results were obtained for [bmim] [BF 4 ]. Cyclic voltammetry data was used to further explain the electrolysis as a function of dilution.

“…Ainsi McCamley et al (2004) ont utilisé un ICP-MS haute résolution (ICP-HRMS) pour mesurer les impuretés de chlore résiduel après synthèse dans 6 liquides ioniques issus de voies de synthèse différentes. Avec une limite de quantification de 10 µg/l, le gain en sensibilité de l'ICP-HRMS au regard des techniques de type électrophorèse capillaire est de 100 fois.…”

Résumé -Après une brève introduction sur la problématique des métaux traces dans l'industrie pétrolière, un retour sur les trois techniques majeures de dosages des métaux traces dans les produits pétroliers est présenté reprenant les travaux effectués dans les dix dernières années. Ainsi les différents types d'introduction, utilisés pour la spectrométrie d'absorption atomique avec four électrothermique (GFAAS), la spectrométrie d'émission atomique par plasma à couplage inductif (ICP-OES) et la spectrométrie de masse par plasma à couplage inductif (ICP-MS), sont repris et comparés en terme de limite de détection atteinte. Les applications sont diverses et touchent la totalité des produits pétroliers, du biocarburant en passant par l'éthanol, aux plus classiques essences et gazoles, allant jusqu'aux produits plus lourds que sont les bitumes. Une revue sur les principaux couplages possibles permet d'entrevoir les différentes possibilités que ces techniques pourront offrir dans les années à venir en terme de spéciation des métaux dans les produits pétroliers.

“…11,12 Moreover, results can be questionable in case of hydrophobic ionic liquids, as these methods typically rely on aqueous media. 13 Optimized detection methods such as chloride sensors, 6 ion chromatography [14][15][16] X-ray uorescence, 17 capillary electrophoresis, 18 cathodic stripping voltammetry, 19 and even inductively coupled plasma mass spectrometry (ICP-MS) 20 have been reported to be employed for residual chloride determination. These methods offer higher sensitivity and accuracy compared to classical wet chemical methods; however, they lack in ease of use and oen require sophisticated sample preparation.…”

Quantification of chloride ion impurities in ionic liquids using ICP-MS analysis

Abstract: The residual chloride ion content in 1-butyl-3-methylimidazolium tetrafluoroborate, [bmim]BF 4 , prepared via various methods, was analysed by ICP-MS. A preliminary analysis was also performed on 1-butyl-3-methylimidazolium hexafluorophosphate, [bmim]PF 6 .
