An aluminum acid-base concentration cell using room temperature chloroaluminate ionic liquids. Dymek, C. J., Jr.; Williams, J. L.; Groeger, D. J.; Auborn, J. J. (Frank J. Seiler Res. Lab., U. S. Air Force Acad., Colorado Springs, CO 80840, USA). J. Electrochem. Soc., 131(12), 2887-92 (English) 1984. CODEN: JESOAN. ISSN: 0013-4651. DOCUMENT TYPE: Journal CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Mixts. of 1-methyl-3-ethylimidazolium chloride (MEICl) [65039-09-0] and AlCl3 m. f25°. Acidic melts, which contain AlCl3 mole fraction R >0.5, can be used as catholytes, with basic melts (R <0.5) as anolytes, in a concn. cell using Al plate electrodes and a microporous polypropylene separator. Gravimetric anal. of electrodes indicates that the anode reaction is: Al + 4Cl- ? AlCl4- + 3e-, and the cathode reaction is: 4Al2Cl7- + 3e- ? Al + 7AlCl4-. The open-circuit potential for the cell Al|AlCl3 (R = 0.37), MEICl||AlCl3 (R = 0.60), MEICl|Al is 1.38 V, and the voltage remains at >1.0 V at const.-current discharge of 1-3 mA for 6-cm2 Al electrodes. Coulometry is combined with gravimetric and compositional anal. (using NMR spectroscopy) of the electrolytes to est. transport nos.

Reaction of chloride ions in low-temperature molten salts and application to the study of complex ion stoichiometry

Reaction of chloride ions in low-temperature molten salts and application to the study of complex ion stoichiometry. Lipsztajn, Marek; Osteryoung, Robert A. (Dep. Chem., State Univ. 65039-09-0 and 7446-70-0 are also occured in this study. New York at Buffalo, Buffalo, NY 14214, USA). Inorg. Chem., 23(12), 1735-9 (English) 1984. CODEN: INOCAJ. ISSN: 0020-1669. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 65, 68, 78 The oxidn. of chloride ions added as a slight excess to a neutral ambient-temp. ionic liq. of either N-n-butylpyridinium chloride or 1-methyl-3-ethylimidazolium chloride mixed with an equiv. amt. of AlCl3 was found to yield an oxidn.wave indicating convective diffusion control at a rotating Pt electrode. The oxidn. wave is linear in the square root of the rotation rate of the electrode and directly proportional to the amt. of chloride in the salt meltup to ~0.1 mol dm-3. Coulometry carried out under conditions similar to those prevailing at the rotating disk electrode indicates the oxidn. of Cl- is to Cl3-. This chloride oxidn. wave in the neutral melt can be applied to study the stoichiometry of chloro-complex species formed, even if the chloro complex is itself not electroactive. Application to the detn. of the no. of chlorides bound to Fe(III) is presented. .
