摘要

Abstract

The solubility of disperse dyes and their mixture in supercritical carbon dioxide is an important property in study and development of supercritical fluid dyeing technology.In this study

solubilities of C. I. Disperse Red 73

C.I.Disperse Blue 183 and their mixture in supercritical CO

are measured at temperatures from 343.2 to 383.2 K and pressures from 12 to 28 MPa with a static recirculation method.Under the experimental conditions for the binary(C. I.Disperse Red 73+CO

or C. I. Disperse Blue 183+CO

) and ternary (C. I. Disperse Red 73+C. I. Disperse Blue 183+CO

) systems

the solubilities increase with pressure.The solubility of C. I.Disperse Blue 183 decreases with the increase of temperature when the pressure is lower than 16 MPa

and the trend is opposite when the pressure is higher than 16 MPa.However

there is no crossover pressure for C.I.Disperse Red 73.The solubilities are also affected by molecular polarity of dyes.The co-solvent effect exhibited in the dissolving process of mixed dyes promotes their dissolution in supercritical CO

.The experimental data of solubilities of C. I.Disperse Red 73

C. I.Disperse Blue 183

and their mixture are correlated with the Chrastil model and Mendez-Santiago/Teja model. The former is more accurate.
