High-pressure densities and P–T–x–y diagrams for carbon dioxide+linalool and carbon dioxide+limonene

A versatile thermodynamic consistency test for incomplete phase equilibrium data of high-pressure gas–liquid mixtures

“…Further analysis was done on these data and detail on this is presented in the next section. For the system CO 2 /Limonene, the data of Gamse and Marr [29] and of Chang and Chen [30] are not acceptable correlated and therefore a different model should be used (TDM). In this last case the comparison of different experimental data presented in the literature for the mixture CO 2 /limonene shows important differences between the data reported.…”

Vapor–liquid equilibria and densities of CO2 with four unsaturated fatty acid esters at elevated pressures

“…Chang et al [7] used a similar calibration procedure. Chang and Chen [8] described in detail the calculation of the composition of the liquid and the vapor phase from the density data. Tables 1-4 present all experimental data concerning four binary systems at 313 and 333 K.…”

Supercritical carbon dioxide extraction of rice bran oil and column partition fractionation of γ-oryzanols

“…Kim et al investigated the time-related mass transfer kinetics of oil components between solid-phase (rice bran) and fluid-phase (carbon dioxide) in supercritical carbon dioxide extraction [16]. Chang et al studied supercritical carbon dioxide extraction kinetics and high-pressure vapor-liquid-phase equilibrium measurements between oil compounds and carbon dioxide [17,18]. Many multi-stage supercritical fluid deacidifications of rice bran oil have been conducted to remove free fatty acids or triglycerides from raffinate oil using a packed column at a middle-high pressure at 333-353 K to increase concentrations of ␥-oryzanols and phytosterols in the oil [19][20][21][22][23][24].…”
