Abstract
The validity of Shinoda's equation for the critical micelle concentration (CMC) of a multicomponent soap mixture (1), ∑ C 1+K g m i μ i ′ exp (m iω/kT) ∑ μ i′ exp(m iω/kT)=C 1+K g mix , has been tested for commercial samples of some long-chain alkyltrimethylammonium bromides. The samples were analyzed by gas-liquid chromatography and CMC's were determined at 25°C by conductivity and surface tension measurements. An average value for K g of 0.65 was obtained from the variation of CMC with total gegenion concentration. Good agreement was found between experimental and theoretical CMC values for mixtures of alklytrimethylammonium bromides containing up to seven components.
