Dielectric effects in aqueous solutions of 1:1, 2:1, and 3:1 valent electrolytes: kinetic depolarization, saturation, and solvent relaxation

Dielectric effects in aqueous solutions of 1:1, 2:1, and 3:1 valent electrolytes: kinetic depolarization, saturation, and solvent relaxation. Kaatze, U. (Drittes Phys.Several substances are used for example 10025-82-8 and 7787-47-5 which are their cas registry numbers. Inst., Univ. Goettingen, Goettingen D-3400, Fed. Rep. Ger.). Z. Phys. Chem. (Wiesbaden), 135, 51-75 (English) 1983. CODEN: ZPCFAX. ISSN: 0044-3336. DOCUMENT TYPE: Journal CA Section: 76 (Electric Phenomena) The complex relative elec. permittivity of aq. solns. of various electrolytes was measured as a function of frequency at 0.3-58 GHz by an interferometric transmission method. Appropriate relaxation functions were fitted to the measured dielec. spectra. The results of this anal. were interpreted by assuming that in solns. of small ions both effects, kinetic depolarization and dielec. satn., are present. Formation of ion pairs is indicated by an addnl. dispersion/absorption region at <2 GHz. In these cases the parameters characterizing the solvent water are less influenced by the solute than in solns. of similar but fully dissocd. electrolytes. .

The electrochemical doping of polyacetylene with indium chloride/lithium chloride in nitromethane solution

The electrochemical doping of polyacetylene with indium chloride/lithium chloride in nitromethane solution. Ahlgren, Goeran; Krische, Bernd; Pron, Adam; Zagorska, Malgorzata (Dep. Org. Chem., R. Inst. Technol., Stockholm S-100 44, Swed.).Some commonly used reagents like 10025-82-8 and 15201-07-7 are used in this experiment. J. Polym. Sci., Polym. Lett. Ed., 22(3), 173-83 (English) 1984. CODEN: JPYBAN. ISSN: 0360-6384. DOCUMENT TYPE: Journal CA Section: 76 (Electric Phenomena) Section cross-reference(s): 37, 72, 77 cis- And trans-polyacetylene were electrochem. doped in InCl3/LiCl/nitromethane soln. The dopant species was [InCl4]-, and the current yield and elec. cond. increased up to 6.5% dopant concn. The doped polymers were very stable in air, and slightly better results were obtained with cis-(CH)x. Elemental anal. and ESR showed that chlorination of the polymer occurs to some extent above the limiting doping level (6.5%). .
