Experimental densities and derived thermodynamic properties of liquid propan-1-ol at temperatures from 298 to 423K and at pressures up to 40MPa

“…(19)). However, at temperatures above the Table 6 Comparison derived values of vapor-pressure and saturated density for propan-1-ol with the data reported by other authors T, K This work Ambrose [104] Cosner [110] Mathews [108] Biddiscom [107] Ramsay [3] Kubichek [109] Deák [113] Vapor Hales [114] Amirkhanov [106] Cosner [110] Kubichek [109] Golubev [19,24] Zakar'yaev [27] Saturated [133] used saturated liquid densities and vapor-pressures as the reference states. However, the temperature dependent reference pressure in the Tait EOS (p 0 = p S (T)) complicates the calculation of the other thermodynamic properties such as caloric or acoustic properties.…”

Isobaric (vapour+liquid) equilibrium for N-methyl-2-pyrrolidone with branched alcohols

“…The branched alcohols (Fluka) were purified by the methods described previously [21]. The purity of the chemicals was assessed by comparing their measured densities (q), refractive indices (n) and boiling points, which were in good agreement with the literature values [2,[21][22][23][24][25], as can be seen in table 1. Densities of pure components were determined with a bicapillary-type (a double stem) pycnometer, of capacity 12 cm 3 .…”

“…The Antoine constants for vapour pressures of the pure components were taken from the literature [2,24,25] and are presented in For sake of clarity, we did not show here the other two models, since three models are merging. The close observation of figure 1 reveals that the curves of three models are overlapping on one another.…”

Complementary vapor pressure data for 2-methyl-1-propanol and 3-methyl-1-butanol at a pressure range of (15 to 177)kPa

“…Table 3 lists the information selected from the literature for the vapor pressures for both congeners studied in this work. Figure 3 compares for 2-methyl-1-propanol the percent deviations from equation (2) with the data included in table 2, in the temperature range of (330 to 400) K. Experimental vapor pressure data from Ambrose and Sprake [16] (some values previously reported by Biddiscombe et al [15]) was represented using equation (2) with a standard deviation of 0.03 kPa, and percent deviations in the range of (À0.06% to 0.27%). If the lowest vapor pressure informed at temperature 343 K is not included, the highest percent deviation decreased significantly to 0.08%.…”
