摘要：

The solubility of disperse dyes in supercritical CO2 was me. jured for three anthraquinone dyes (i.e., Celliton fast blue B, 1-amino-2-methylanthraquinone, and 1-(methylamino)anthraquinone) and two azo dyes (i.e., disperse red 1 and 4-[4-(phenylazo)phenylazo]-o-cresol). Measurement was carried out at 313.15 K, 353.15 K, and 393.15 K and (10, 15, 20, and 25) MPa in an autoclave-type phase equilibrium apparatus. The data were modeled by a semiempirical correlation. For all the dyes, the solubility increased with increasing density of supercritical CO2. The anthraquinone dyes show higher solubility than the azo dyes.
