Hexadecylpyridinium bromide solutions

Over recent years the question of whether or not surfactants form aggregates similar to micelles and mesophases in other polar solvents has received considerable attention [168-191]. The solvents concerned are polar liquids such as glycerol, ethylene glycol, formamide or ethyl ammonium nitrate (a molten electrolyte at ambient temperature). The answer is yes, but the thermodynamics of the aggregation process is somewhat different. Figures 40 and 41 show measurements of EMF in hexadecylpyridinium bromide solutions where water and ethylene glycol are solvents.
