Abstract
The solubility of a reactive disperse dye, which was modified from CI Disperse Red 17 with a derivative of 1,3,5‐trichloro‐2,4,6‐triazine as the reactive group, was investigated in supercritical carbon dioxide fluid by employing a batch system equipped with an online spectrophotometer. The investigations were carried out at pressures of 7.5–25.0 MPa, temperatures of 333.15–413.15 K and an equilibrium contact time of 120 min. As revealed from the experimental results, the solubility of the reactive disperse dye increased with pressure in different isotherms, and decreased with temperature. Furthermore, the experimental solubility data were correlated successfully with semi‐empirical models – Chrastil and Del Valle–Aguilera equations, respectively – at various temperatures and pressures.
