Experimental Values

Excess molar volumes and excess refractive indices of the n-octanol + 1,4-dioxane + 2-butanol system and the three corresponding binary mixtures have been determined at 298.15 K by measuring densities and refractive indices. Different expressions exist in the literature to predict these excess properties from binary data. An estimation of excess molar volumes is also evaluated using a modified Heller equation which depends on the refractive indices of the mixtures. A comparison of the predictions of different methods with the experimental values of the physical properties has been made.Key words: excess molar volumes, densities, refractive indices, n-octanol, 1,4-dioxane, 2-butanol, ternary system.

Densities, refractive indices and viscosities of the binary mixtures of dimethyl phthalate (or dimethyl adipate) + tetrahydrofuran have been measured at eight temperatures (288.15 to 323.15 K) and atmospheric pressure. All measurements were performed using an Anton Paar DMA 5000 digital vibrating-tube densimeter, Anton Paar RXA 156 refractometer and Anton Paar SVM 3000/G2 digital Stabinger viscometer, respectively. From the experimental densities, refractive indices and viscosities, the excess molar volumes, VE, deviations of refractive indices, DnD, and viscosity deviations, Dh, were calculated.
