Volumetric properties of (1-propoxypropan-2-ol+water) mixtures between (283 and 303)K: The effect of branching on alkoxyalcohols

Refractive Index of Liquid Mixtures: Theory and Experiment

“…Densities at all of the mole fractions and temperatures have recently been reported by Santos et al [7] as experimental values for the most part. However, for 19 mixture compositions, which are identified in Table S1 of the Supporting Information, densities were estimated by using the Redlich-Kister a i coefficients in Table 2 of ref.…”

“…However, the previous volumetric analysis of this system [7] revealed that, in this composition segment, the excess molar isobaric expansion,…”

“…However, for 19 mixture compositions, which are identified in Table S1 of the Supporting Information, densities were estimated by using the Redlich-Kister a i coefficients in Table 2 of ref. [7]. Since pure-component molar volumes are needed to calculate ideal molar volumes and volume fractions, in Table S2 of the Supporting Information we provide these data [7] at the working temperatures.…”

“…[7]. Since pure-component molar volumes are needed to calculate ideal molar volumes and volume fractions, in Table S2 of the Supporting Information we provide these data [7] at the working temperatures. Here we quote that, at 298.15 K, n A * = 1.41007, V A * = 134.161 cm 3 mol À1 , n B * = 1.33250 and V B * = 18.0687 cm 3 mol…”

“…The volumetric properties of aqueous mixtures of the former amphiphile have been studied [7] recently in our laboratory and those of the latter series have also been examined in detail. [8] The thermodynamic analysis of our refractive index data in conjunction with previously published density data [7] reveals two prominent features. Firstly, pear-shaped curves in plots of excess refractive indices against excess molar volumes exhibit three zones of different mutual change.…”
