During which, a high pressure experimental apparatus for determining ternary phase equilibrium was set up, and by using it, the equilibrium concentration partition coefficients of disperse orange 25 between supercritical CO2 and polyester fibres (terylene) at the temperature of 353、373 and 393 K and under the pressures ranging from 17 MPa to 32 MPa were determined respe.
