Abstract

Accurate density values, at ambient pressure, were obtained in aqueous binary mixtures of 2-ethylaminoethanol (EEA) over the whole composition range at intervals of 5 K in the temperature range between 283.15 and 303.15 K. To gain some insight into the several aggregation patterns present in these mixtures, calculation of excess molar volumes of the mixture, apparent molar and excess partial molar volumes of both components were made over the entire composition and temperature ranges. Thermal expansibility effects on this amphiphile/water mixture are analysed in terms of excess molar isobaric expansions EEP,m for the mixture and of excess apparent molar isobaric expansions EEP,φ,i for both chemical substances in the mixture. Limiting excess partial molar isobaric expansions have been calculated as well, from the temperature dependence of limiting excess partial molar volumes. An analytical method based on Redlich–Kister fitting equations for VEm as a function of the mole fraction, has been used to obtain VE,∞i. The excess properties are referred to a thermodynamically defined ideal liquid mixture. Interesting insights into the mixing process are gained from the visual impact of plots showing the composition and temperature dependence of different excess molar thermodynamic properties.
