Solubility profile of xanthone (x1) in a mixture of tricaprin (x2): tricaprylin (x3). Markers: experiment; smoothed line: local composition regular theory model (LC-RST) with significant fitting parameters (l23 was removed); dashed line: Wilson model. : 75 °C (orange);
: 60 °C (green);
: 45 °C (red);
: 30 °C (blue). x2 (solute free) is the mole fraction of tricaprin (2) in the mixed solvent that is free of xanthone. (Raw data: Table S3). Purple: 90 °C (predicted with LC-RST)
