This short review highlights the solubility and correlation of four azobenzene derivatives, which have similar chemical structures, available in the literature. At the same phase equilibrium (at the temperature of 353.15 K), the solubilities of four azobenzene derivatives in supercritical carbon dioxide followed in the order of Disperse Red 82 > Disperse Red 13 > Disperse Blue 79:1 > Disperse Red 1. Five different kinds of density-based models were used to correlate the solubility data. Moreover, the solubilities of four azobenzene derivatives were also correlated thermodynamically by the model of the regular solution with the Flory–Huggins theory. It was found the Sung-Shim model (four parameters) has the lowest median AARD of 12.02 % of the solubility data over the entire conditions.
