Vapor-Liquid Equilibria for the Methyl Oleate and Methyl Stearate Binary System.

Estimation of Vapor Pressures and Enthalpies of Vaporization of Biodiesel-Related Fatty Acid Alkyl Esters. Part 2. New Parameters for Classic Vapor Pressure Correlations

“…Except for two compounds ("ME-C12:0" and "ME-C16:0"), the parameters proposed in this work showed the highest accuracy in comparison to the others. Even for these specific esters, our results were almost as accurate as the best: 0.42% 4 SMM X Rose/Supina 5 RS X Rose et al 6 RAJS X Silva et al 7 SFMK X Tang et al 8 TDHX X Rose/Schrodt 9 RV X Freitas et al 10 FOLC X Sahraoui et al 11 SAH X Duan et al 12 DU X X Yuan et al 13 YHZ X…”

The Use of Antioxidants to Improve Vapor Pressure Measurements on Compounds with Oxidative Instability: Methyl Oleate with tert-Butylhydroquinone

“…There is a limited amount of p sat data for methyl oleate with which to compare our measurements. Although there are a couple of noteworthy high-temperature studies, , there are only two reports of p sat data for methyl oleate in or near the temperature range that we have investigated. A report by Krop et al gives a single data point at 298.15 K .…”

“…There is a limited amount of p sat data for methyl oleate with which to compare our measurements. Although there are a couple of noteworthy high-temperature studies, 11,12 there are only two reports of p sat data for methyl oleate in or near the temperature range that we have investigated. A report by Krop et al gives a single data point at 298.15 K. 14 The report by Lipkind et al gives a correlation of data for the temperature range 298.15 to 450 K. 15 (An important detail about calculations with the correlation of Lipkind et al is given elsewhere.…”

“…When working with samples of limited stability, procedures to detect sample decomposition must be in place. An excellent, underutilized , way to detect sample decomposition is to do replicate p sat measurements on the same sample. Sample decomposition will usually change the measured value of p sat over time; therefore, the last measurement in any series should replicate the first measurement in the series.…”

Liquid–(Liquid)–Vapor Equilibrium of Solvents (P-Xylene, Methyl Hexadecanoate, and Methyl Oleate), Binary Systems (Water + Solvents), and Ternary Systems (Water + Methyl Hexadecanoate + Model Molecule of Tar) Issued from the Biomass Gasification Process

“…Our experimental results are in total agreement with the different authors, and a systematic error of 1.5% between the experimental and literature vapor pressures was observed. 13−18 Also, experimental vapor pressures of methyl hexadecanoate and methyl oleate were compared to those reported by Scott et al, 19 Bonhorst, 20 and Rose et al 21 A deviation of 2% is observed between the experimental vapor a Expanded uncertainties "U" with a confidence level of 95%, which is a combination of u(T) = 0.02 K; u(m) = 0.1 g (weighing of the mixtures); u(apparatus) = 0.03P/Pa for pressures lower than 600 Pa; u(apparatus) = 0.01P/Pa for the pressure range: 600 < P/Pa < 1300; and u(apparatus) = 0.003P/Pa for the pressure range: 1.3 < P/kPa < 200. b (%) 100 where P is the vapor pressure, R is the gas constant, T is the absolute temperature, and ΔH and ΔS indicate enthalpy and entropy changes, respectively. The calculated enthalpies for the three solvents and the constants A and B as well as the mean deviation values using eq 3 are listed in Table 4.…”
