High-pressure phase equilibrium data for the carbon dioxide + methyl esters homologous series and SAFT-VR Mie modelling

High-Pressure Phase Behavior of CO2 + (C12/C14 n-Alkane and/or C8/C10 Carboxylic Acid and/or C12/C14 Methyl Ester) Systems

“…Although the experimental setup and procedure have been extensively verified, − ,,,,− it is prudent to ensure that any new operator is able to produce reliable data by using the equipment. To this end a verification system, CO 2 + 1-octanol, was measured by the present authors and compared to a multitude of literature sources.…”

“…Comparison of the pressure, P , versus solute fraction, w 1 , at 328 K for (a) mixture 5, (50 wt % n -dodecane + 50 wt % methyl dodecanoate) (1) + CO 2 (2); (b) mixture 6, (50 wt % n -tetradecane + 50 wt % methyl dodecanoate) (1) + CO 2 (2); (c) mixture 7, (50 wt % n -dodecane + 50 wt % methyl tetradecanoate) (1) + CO 2 (2); and (d) mixture 8, (50 wt % n -tetradecane + 50 wt % methyl tetradecanoate) (1) + CO 2 (2). The corresponding constituent binary n -alkane system (CO 2 + n -dodecane or CO 2 + n -tetradecane) are represented by unfilled markers, while the corresponding constituent methyl ester binary (CO 2 + methyl dodecanoate or CO 2 + methyl tetradecanoate) is represented by filled markers.…”

“…Figure 11. Comparison of the pressure, P, versus solute fraction, w 1 , for mixture 8, (50 wt % n-tetradecane + 50 wt % methyl tetradecanoate) (1) + CO 2(2), at (a) 308.15 and (b) 348.15 K. The corresponding constituent binary n-alkane system (CO 2 + n-tetradecane38 ) is represented by unfilled markers, while the corresponding constituent methyl ester binary (CO 2 + methyl tetradecanoate21 ) is represented by filled markers.…”
