“…In this figure, the large deviations of the data of ref 2 at different temperatures that had similar deviations for the 1-propanol + water system may be due to density measurements at different temperatures. The excess molar enthalpy of this system is negative and positive 9 and the excess Gibbs energy 9 and viscosity deviation is positive 26 and they formed a minimum boiling point azeotrope. 27 Considering these observations, the negative values of V m E over the entire range of mole fraction may be attributed to accommodation of water molecules in the propanol network.…”

“…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.
