“…Let us compare the experimentally obtained peculiarity in the refractive index behavior with the peculiarities in the intensity of molecular light scattering [21,22] and the contraction behavior [1][2][3][4]. As one can see, the center of the concentration interval, in which the behavior of the refractive index is unusual, coincides with the position of the special point for the aqueous ethanol solution.…”

The concentration dependences of the refractive index in aqueous ethanol solutions at equilibrium have been studied experimentally. Special attention was paid to their behavior in a vicinity of the peculiar point defined as the intersection point of the concentration dependences of the contraction measured at different temperatures or as a point, at which the intensity of molecular light scattering has a maximum. The refractive index is found to noticeably deviate from its reference values in a vicinity of the peculiar point, 0.05 < < 0.1 (is the mole fraction of ethanol). This effect reflects the fact that the equilibrium properties of the solutions concerned are established only during a few weeks. Arguments that the system becomes microinhomogeneous in this concentration interval are presented. K e y w o r d s: water-alcohol solutions, refractive index, microinhomogeneous structure.

“…In the x 2 a -x 2 b region, where our data suggest a clustering of alcohol molecules, many properties of these mixtures show a remarkable change. In this region of composition a maximum is found in sound absorption 5 and X-ray 14 and light 15,16 scattering. All these effects suggest clustering of the mixture components to form microscopic heterogeneities.…”

This paper reports on critical micelle concentrations and enthalpies of micellization of n-butoxyethanol in water at three different temperatures (5, 25, and 45°C) as determined by means of a sensitive microcalorimeter. The experimental enthalpies are compared with those calculated from the temperature dependence of the critical micelle concentration by using the phase separation model of micelle formation. Enthalpies and entropies of micelle formation are both positive and decrease as the temperature is raised indicating the hydrophobic effect in the formation of n-butoxyethanol microaggregates. These calorimetric results provide no indications of intermicellar interactions, while indicating a monomer-monomer repulsive interaction in the premicellar region.
