“…Ion-solvent interactions were extensively investigated in a number of mixed solvents using different techniques 2,3 . The aim of this work is to determine the solvation characteristic of Bu 4 4 , N,N-dimethylformamide, acetonitrile and n-butyronirile and their binary mixtures 5 . Mixtures of DMSO+MeOH are therefore expected to be good solvents for a comparative study of the solvation behaviour of tetraalkylammonium ions.…”

“…The values of molar conductivities of a set of TAA + ions with n from 1 (or 2) to 7 (or 8) are available in several solvent systems, ,,, but in the case that the viscosity is high, the Λ 0 values are rather small and relatively close to each other. The same concerns the data in nitrobenzene, 1,2-dichlorobenzene, sulfolane, ethylene glycol, and propylene carbonate .…”

Conductivity and Dissociation Constants of Quaternary Ammonium Perchlorates and Picrates in 4-Methyl-pentan-2-one

The dissociation of 14 ionophores, namely, seven symmetrical (C 1 to C 7 ) and five asymmetrical quaternary ammonium perchlorates and two tetraalkylammonium picrates (all with linear hydrocarbon chains), in 4-methyl-pentan-2-one was studied at 25 °C (ε r ) 12.92) using the conductance method. The values of the association constants of the quaternary ammonium cation, Ct + , with ClO 4 vary from (7.4 ( 0.3) • 10 3 L • mol -1 for tetramethylammonium to (2.4 ( 0.1) • 10 3 L • mol -1 for tetrahexyl-and tetraheptylammonium; a distinct dependence on the size of the Ct + , especially for symmetrical cations, is evident. The values of the limiting molar conductivities Λ 0 /S • mol -1 • cm 2 vary from 122.8 to 90.0 (( 0.7). The plot of Λ 0 versus the reciprocal cube root of the total van der Waals volume of the cations, V Ct -1/3, is close to linear up to tetrapentylammonium and hexadecyltrimethylammonium, while for larger cations (with 21 to 28 carbon atoms) the Λ 0 values stay practically constant. At the same time, symmetrical and asymmetrical cations with the same V Ct values possess equal mobility. † Part of the "Josef M. G. Barthel Festschrift".
