ABSTRACT
The solubilities of color index disperse yellow 232 and 184 and their modified forms in supercritical carbon dioxide have been measured at different temperatures of (308, 318, 328, 338, and 348) K and in the pressure range of (12.1 to 35.5) MPa. Solubility data were correlated using four semiempirical models (Chrastil, Kumar-Johnston, Bartle, and Mendez-Santiago-Teja). A comparison among the four models revealed that these models showed good correlations of the solubility data with an overall average absolute relative deviation (AARD) of 0.155, 0.16, 0.184, and 0.157, respectively. Using the correlation results, the enthalpies of dye-CO2 solvation and dye vaporization were separately approximated. Their values were found to be in the range of (12.5 to 19.4) and (70.6 to 102.7) kJ*mol-1.
