Sphere to rod transitions in homologous alkylpyridinium salts: A Stauff-Klevens-type equation for the second critical micelle concentration was written by Gonzalez-Perez, A.;Varela, L. M.;Garcia, M.;Rodriguez, J. R.. And the article was included in Journal of Colloid and Interface Science in 2006.Electric Literature of C17H30BrN This article mentions the following:
The authors analyze the dependence of the 2nd critical micelle concentration (2nd cmc) of ionic amphiphiles on the number of atoms in the hydrocarbon mol. chain, nc. A mol. thermodn. model for the interaction energy between the end caps of rodlike micelles, g(N), is introduced and the linear dependence of this object on n c analyzed, thus leading to a Stauff-Klevens-like behavior of the 2nd cmc. The predictions agree with previously reported data for n-alkyldimethylbenzylammonium chloride (CnBACl) for n-alkylpyridinium chloride (CnPyCl) and n-alkyltrimethylammonium bromide (CnTABr) at 35°. These conclusions are reinforced by the conductivity, d., and ultrasound velocity measurements of the 2nd cmc of several CnPyCl (n = 12, 14, 16) and n-alkylpyridinium bromides (CnPyBr, n = 12, 14, 15, 16) presented. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Electric Literature of C17H30BrN).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Electric Literature of C17H30BrN
