General Description

Triethylhexadecylammonium bromide is a quaternary ammonium compound with the chemical formula C24H52BrN, commonly used as a surfactant and phase transfer catalyst. It is a long-chain quaternary ammonium salt, where the alkyl group consists of a 16-carbon chain. It is often used in organic synthesis and catalysis, as well as in pharmaceutical and cosmetic formulations. It has surfactant properties, meaning it can lower the surface tension of a liquid, making it useful in various industrial and scientific applications. Additionally, triethylhexadecylammonium bromide can also be used as a cationic detergent for the solubilization and purification of proteins and DNA.

Effect of Head-Group Size on Micellization and Phase Behavior in Quaternary Ammonium Surfactant Systems

The micellization and phase equilibria in aqueous solutions of cationic quaternary ammonium bromide surfactants of the type alkyltrimethyl-, -ethyl-, -propy-, -butyl-, and -pentylammonium bromide have been investigated as a function of alkyl chain length, electrolyte concentration, and temperature.A large isotropic (micellar) phase is observed in triethyl- and tripropylammonium surfactants, which demixes into two conjugate phases on warming in the case of the alkyltributylammonium bromides.Liquid-liquid phase separation is also observed for tetradecyltripentylammonium bromide.Critical micelle concentrations are found to decrease with increasing hydrophobicity of the surfactant ion, but the free energy of micellization of tetradecyltributylammonium bromide is the same as that of tetradecyltrimethylammonium bromide over a range of temperatures.Some evidence is found for the formation of premicellar aggregates in tributylammonium surfactants at elevated temperatures, consistent with significant polydispersity and changing monomer concentrations observed previously.The results are discussed in terms of the hydrophobic and electrostatic contributions of the free energy of micellization, and some interferences are drawn regarding the nature of the interactions which give rise to phase separation.
