Uner, Osman published the artcileMicellization and thermodynamics study of n-alkyl-4-methylpyridinium bromides in water and mixed water-ethanol media, HPLC of Formula: 143-15-7, the publication is Journal of Molecular Liquids (2022), 118765, database is CAplus.
The micellization behaviors of n-decyl-4-methylpyridinium bromide, n-dodecyl-4-methylpyridinium bromide, and n-tetradecyl-4-methylpyridinium bromide were studied in water and mixed water-ethanol media by using conductivity measurements over the temperature range of 293.15-318.15 K. The critical micelle concentrations (CMC) of all n-alkyl-4-Me pyridinium bromides studied increased with increasing temperature, but they decreased with increasing hydrocarbon chain length. Their CMC values of n-decyl-4-methylpyridinium bromide, n-dodecyl-4-methylpyridinium bromide, and n-tetradecyl-4-methylpyridinium bromide in water at the temperature range of 293.15-318.15 K were determined as in the range of 43.62-46.42, 10.45-11.57, and 2.78-3.20 mM, resp. Moreover, the lowest CMC values of n-decyl-4-methylpyridinium bromide, n-dodecyl-4-methylpyridinium bromide, and n-tetradecyl-4-methylpyridinium bromide were found with 15, 5, and 5 vol% ethanol additions, resp. The calculated neg. ΔGm0 and ΔHm0 values proved that their micellizations in water and mixed water-ethanol media were spontaneous and exothermic. Also, ΔGm0 values became the more neg. with the longer the hydrocarbon chain length. Furthermore, their micellization processes in water were determined to be entropy controlled, however enthalpic contributions in the mixed water-ethanol systems started to predominate with increasing ethanol concentrations and/or temperature
