The critical micelle concentrations of decylpyridinium chloride in aqueous solutions have been determined by the electrical conductance measurements in the range of 10°-50℃. The temperature variation of the critical micelle concentrations has shown the minimum at the vicinity of 15℃. The Clausius-Clapeyron type equation of log (c.m.c.) versus temperature has been established. The values ΔHm and the other thermodynamic properties associated with micelle formation have been determined using the above equation and compared with that of dodecylpyridinium chloride and dodecylpyridinium bromide.
