Thermodynamic properties of {xCH3OH +(1−x)H2O} withx= (1.0000 and 0.4993) in the temperature range from 320K to 420K at pressures up to 200MPa

Excess molar volumes VmE, isothermal compressibilities k, and thermal expansivities α of {(1−x)H2O+xCH3OH} at T=(298.15 to 523.15) K and pressures up to 60 MPa

“…The excess molar volumes V E m of the present work are compared with the experimental results of Osada et al [17] in 28 points at T ¼ (323. 15, 348.15, 373.15, and 398.15) K and p ¼ (5,10,20,30,40,50, and 60) MPa pressures.…”

“…The excess molar volumes V E m were compared with reference values of [4,[7][8][10][11][12][13]16,17] in the regions of overlap. Figure 4 shows the comparison of literature and present values at T ¼ 298:15 K and p ¼ 0:1 MPa.…”

“…The densities for water from [20] and methanol from [17,18,[22][23][24] were used during the calculations. Figures 1-3 show the excess molar volumes V E m of {(1 À x)H 2 O+xCH 3 OH} against pressure at x ¼ 0:50 mole fraction, against temperature at x ¼ 0:25 mole fraction, and against mole fraction at p ¼ 20 MPa.…”

“…The previous experimental works [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] on the excess molar volumes V E m , isothermal compressibilities k, and thermal expansivities a are tabulated in table 1. Many papers include a small range of state parameters.…”

The thermal properties of a water-methanol system with a composition of 0.5 mass fraction at temperatures from 373.15 to 673.15 K and pressures up to 60 MPa

“…At temperatures between Table 1). Analysis of the available data on the thermal properties of aqueous solutions of methanol reveals that the majority of investigations were limited to the temperature of 573.15 K [2][3][4], at which the effect of thermal decomposition on the thermal properties of a system is insignificant (within the experimental accuracy).…”
