Volume behavior of mixed micelles of dodecyltrimethylammonium chloride and bromide [PDF]

Journal of Solution Chemistry, 1991
Densities of aqueous solutions of mixtures of dodecyltrimethylammonium chloride (DTAC) and dodecyltrimethylammonium bromide (DTAB) have been measured as a function of total molality at constant composition and the apparent molar volumes of the mixtures were derived from the density data.
