Densities of toluene, of butanol and of their binary mixtures from 298 K to 400 K, and from 0.5 to 20.0 MPa

Compressed liquid densities of 1-butanol and 2-butanol at temperatures from 313K to 363K and pressures up to 25MPa

“…The maximum relative deviations are ±0.2% as can be seen in figure 4 where dashed lines limited this range of deviations, only some points at 348.2 K reported by Wong and Hayduk [30] did not follow this trend being the deviations higher compared to the remaining data, these behavior was also found with the correlation of Ihmels and Gmehling [13]. The best agreement was observed with the reported by Kubota et al [29] and p /MPa [22]; ,, Vasilkovskaya et al [25]; h, Goluveb et al [27]; }, Albert et al [28]; n, Kubota et al [29]; q, Wong and Hayduk [30]; d, Ulbig et al [33]; ·, Ihmels and Gmehling [13]. by Ihmels and Gmehling [13] since the deviations with these sets of data were represented with the uncertainty announced for the BWRS EoS.…”

“…Most of the data of Golubev and Bagina [22] were in good agreement only a point at 20 MPa differs for the trend founded for the relative deviations for this set of data. The relative deviations with the data reported Albert et al [28] were according to the uncertainty of ±0.1% for the density measurements reported by the authors [28]. The systematic deviations with the data reported by Vasilkovskaya et al [25] can be due to the lower purity of the 1-butanol used (99.84%).…”

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

“…A Tait type EOS for propon-1-ol was also developed by Kubota et al [33]. This type of EOS was successfully applied by Sun et al [77] for other alcohols such as methanol, butanol and other liquids [78][79][80][81][82][83][84][85][86][87][88][89].…”

A novel pycnometer for density measurements of liquids at elevated temperatures

“…Many instruments have been developed to measure density at high temperatures and pressures. A widely used flow pycnometer is the vibrating-tube densitometer [1,[9][10][11][12][13][14][15]. This instrument uses the damped oscillations of a vibrating-tube (of known volume), to determine the mass of fluid flowing through it at given conditions.…”
