The measuring and correlating of the phase equilibrium data (solubility) in supercritical CO2/disperse dye binary system are a key to the foundational research and technologic development of supercritical fluid dyeing (SFD). The high-pressure experimental apparatus was set up and the solubility values of disperse red 60 in supercritical CO2 at 353-393K and 15-30MPa were measured. The ?zcan's formula was used to correlate the experimental solubility data. The calculated results are well close to the experimental solubility values. The relative deviations are all less then 9.3%. The results show that the pressure, temperature and density of system have great effects on solubility of disperse dye in supercritical CO2. The ?zcan's formula is fit for correlating of disperse dye solubility in supercritical CO2.
