Studies on solubility of disperse dyes in supercritical carbon dioxide

LU Tong-qing

Abstract

The technological factors, such as the circulation time, the pressure and temperature of the fluid, which effect on the solubility of disperse dyes in supercritical carbon dioxide, have been studied. Then the solubility of the purified and commercial disperse dyes has been determined under pressure 30 MPa and temperature 120℃ in the supercritical carbon dioxide, and the effects of the structure of dyes on their solubility have been discussed further.
