Acoustic and Thermodynamic Properties of Ethanol from 273.15 to 333.1 5 K and up to 280 MPa

PVT measurements of liquid ethanol in the temperature range from 310 to 363 k at pressures up to 200 MPa

“…At 318.138 K, the data of Gupta and Hanks [12] exceed the present results by 0.14% at 22.063 MPa, and fall below them by 0.07% at 2.758 MPa. At 323.137 K the data of Sun et al [9] agree with the present results of series 2 within +0.1%. At 323.137 K the data of Ozawa et al [11] and those of Kubota et al [10] are lower than the present results by 0.11-0.19 and by 0.12-0.53%, respectively.…”

“…The data of Sun et al [9] at 313.140 K exceed the present results by 0.03-0.12%. At 318.138 K, the data of Gupta and Hanks [12] exceed the present results by 0.14% at 22.063 MPa, and fall below them by 0.07% at 2.758 MPa.…”

“…We measu,'ed densities lbr five pressures at 310.000 K by three series, for three pressures at [9][10][11][12] from the present results. The data of Sun et al [9] at 313.140 K exceed the present results by 0.03-0.12%.…”

Densities for liquid ethanol in the temperature range from 310 K to 480 K at pressures up to 200 MPa

“…Comparison of the density measurements with the literature values at temperatures between T = 313 K and T = 363 K was reported previously. (14) The density deviations of the data by Sun et al (9) and those by Gupta and Hanks (4) from the present measurements are less than 0.0016·r. The density deviations of the data by Ozawa et al (5) and those by Kubota et al (8) are less than 0.0038·r and 0.0053·r, respectively.…”

Correlation and prediction of biodiesel density for extended ranges of temperature and pressure

“…However, access to the values is difficult and uncertain because they are presented in graphic form. Their biodiesel had practically the same composition of N21 biodiesel, which was also measured up to 35 MPa for temperatures between 293 K and 373 K. Dzida and Prusakiewicz [25] measured density from 263 K up to 373 K at atmospheric pressure and the values at pressures up to 100 MPa in the range (293-318) K were calculated following a numerical procedure proposed by Sun et al [48]. However, the FAMEs profile was not presented, neither by Nikolić et al [23] who made density measurements for rapeseed biodiesel at 293 K and up to 160 MPa and presented density data in graphic form, which for our purpose was useless.…”
