“…The water content, measured for each sample by Karl-Fisher titration, was always found to be less than 0.002 mass%. Further, the purities of liquids were checked by comparing the densities, viscosities, and speeds of sound at 298.15 ± 0.01 K with their corresponding literature values [18][19][20][21][22][23][24][25][26][27][28][29] in table 1.…”

“…This work is part of a systematic research on transport and volumetric properties of aqueous mixtures with short alcohols based on experiments and molecular simulations. − Here, the density, excess, and partial molar volumes of the quaternary mixture water + methanol + ethanol + propan-2-ol and all of its four ternary subsystems are presented. The six binary subsystems have been thoroughly studied in the literature, for example, in refs – ; therefore, only selected compositions of these were measured for validation purposes.…”

“…The volumetric properties of the ternary subsystem water + methanol + ethanol have been studied thoroughly in the literature, ,,− and Zarei et al . as well as Mori et al proposed Redlich–Kister- and NRTL-type correlations for its excess volume. Wei and Rowley studied the density and kinematic viscosity of the ternary mixture methanol + ethanol + propan-2-ol but only correlated the latter.…”

The density of the quaternary mixture water + methanol + ethanol + propan-2-ol and its four ternary and six binary subsystems is measured over a wide composition range at ambient temperature and pressure, that is, 298.15 K and 0.1 MPa. The resulting molar volume data are correlated with a response surface model, consisting of linear, quadratic, bilinear, and trilinear interaction terms. The density values obtained with this correlation are compared to molecular simulation results and experimental literature data. Further, the excess molar volume and the partial molar volumes are determined for the ternary and quaternary mixtures. The analytical solution for the partial molar volumes of a quaternary mixture for the response surface model is also given.

“…It also has become more popular to use in solar thermal systems. 1 Review of the literature show that volumetric properties of binary mixtures of 1-propanol + water and 2-propanol + water have been reported, [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] but with regard to the ternary mixtures of 1-propanol + 2-propanol + water there are practically no experimental values.…”

Excess molar volume, V m E , and excess partial molar volume, V i E , of the ternary mixtures of 1-propanol (1) + 2-propanol (2) + water (3) and of two binaries of 1-propanol (1) + water (3) and 2-propanol (2) + water (3) have been investigated from the density, F, measurements over the entire range of composition at temperatures (293.15, 303.15, 313.15, and 323.15) K and at ambient pressure (81.5 kPa). The limiting values of the excess partial molar volumes at infinite dilution, V i E,0 , and thermal expansion coefficients, R, of the pure component are also evaluated. The systems exhibited negative values of V m E that increase with increasing temperatures. The excess molar volumes were correlated with the Redlich-Kister equation and the Cibulka equation for binary and ternary systems, respectively. The excess molar volumes, V m E , of the binary mixtures were compared with values from the literature in the region of overlap.
