Abstract

The thermodynamics of micellization of a new series of ionic surface-active agents, dimethyl alkyl-2-deoxy-2-epi-inosityi-ammonium chlorides, has been examined, A minimum in the critical micelle concentration versus temperature has been observed at $25^{\circ}C$ It has been found that the standard entropy of micellization is always positive showing that miceliization is governed by the gain in entropy associated with the removal of the monomer from an aqueous environment to the micelle over a $15^{\circ}C$ to $45^{\circ}C$ temperature while governed by enthalpy directed process below $25^C{\circ}$.
