Interaction in mixed micellization of sodium N-tetradecanoylsarcosinate with ionic and nonionic surfactants was written by Varade, D.;Bahadur, P.. And the article was included in Journal of Dispersion Science and Technology in 2005.Name: 1-Dodecylpyridin-1-ium bromide This article mentions the following:
The interaction of aqueous binary mixtures of an N-acyl amino acid based anionic surfactant, sodium N-tetradecanoylsarcosinate (C14-sarcosinate), in the presence of cationic, anionic, and nonionic surfactants was studied by surface tension and viscosity measurements. The cationic surfactants dodecyltrimethylammonium bromide (DTAB), tetradecyltrimethylammonium bromide (TTAB), hexadecyltrimethylammonium bromide (CTAB), dodecylpyridinium bromide (DPyB), and hexadecylpyridinium bromide (CPyB), the anionic surfactant sodium dodecyl sulfate (SDS), and the nonionic surfactant Triton X-100 were used. The critical micelle concentration (CMC) values of pure surfactants and their mixtures were determined by surface tension measurements at different mixed ratios. The interaction parameters that measure the interaction between the surfactant mols. in the mixed micelle were computed by Rubingh’s approach. The viscosity of the mixed systems of C14-sarcosinate with cationic surfactants (having higher chain length) at various mole fractions suggested a growth in mixed micelles with maxima at 0.4 mol fraction of C14-sarcosinate. The mixed micelles remain spherical with SDS and Triton X-100. These changes in viscosities are due to changes in the microstructure of the mixed aggregates. Triton X-100 shows a steep rise in cloud point in the presence of C14-sarcosinate. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Name: 1-Dodecylpyridin-1-ium bromide).
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. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Name: 1-Dodecylpyridin-1-ium bromide
