摘要
The solubility of disperse dyes, CI disperse red 60 and CI disperse orange 3 in supercritical carbon dioxide have been measured at temperatures from 323.7 K to 413.7 K and pressures from 100 bar to 300 bar using a now-type equilibrium cell. The solubility data are correlated with an expanded liquid model which needs no critical properties of dyes, as well as an empirical equation.
