Ion-pair and triple-ion formation of some tetraalkylammonium iodides in n-hexanol and its binary mixtures with o-toluidine

Amphiphile Behavior in Mixed Solvent Media I: Self-Aggregation and Ion Association of Sodium Dodecylsulfate in 1,4-Dioxane–Water and Methanol–Water Media

“…According to our information, the formation of ion-pair and triple-ion of colloidal electrolytes has not been reported. We may mention that the herein-reported results are comparable to the recently documented results on the tetralkylammonium iodides in the solvent media of (CCl 4 + PhNO 2 ), (1,4-dioxane + tetrahydrofuran), (dichloromethane + N , N - dimethylformamide), and ( o -toluidine + n -hexanol); sodium salts (such as NaBPh 4 , NaBF 4 , and NaClO 4 ) in a 1,2-dimethoxyethane medium; and lithium salts (such as LiCl, LiBr, LiClO 4 , LiBF 4 , and LiAsF 6 ) in a 1,2-dimethoxyethane medium . In Table , the C P , C T , and Λ values at the conductance minimum and maximum (marked by m and M in the Figure B plot at 88 vol %, respectively) are reported in bold font.…”

Coordination phenomena of alkali metal, alkaline earth metal, and indium ions with the 1,3,6-naphthalenetrisulfonate ion in protic and aprotic solvents

“…In aprotic solvents such as acetonitrile (MeCN), the specific coordination reactions between alkali metal or alkaline earth metal ions with some simple ions such as halides (Cl -, Br -) [4,5], tropolonate [6], sulfonates, and carboxylates [7] have been demonstrated by means of various analytical methods. With the increasing concentration of M + (an alkali metal ion), the specific reaction may proceed in three steps: at first, a half equivalence or less than that amount of M Fuoss and Kraus [9] have introduced the concept of triple ion between free ions and triple ions in the solvents of low permittivity (ε r < 10 or 23.2).…”
