Abstract
The solubility of ten disperse dyes in supercritical carbon dioxide (SC-CO2) was measured using a modified Suprex PrepMaster SFE apparatus and Varian Cary 3E UV¯Visible spectrophotometer. These measurements were made over a pressure range of 200¯400 atm, at 50¯100°C. The results were combined with relevant solubility data from previous studies, and were used to develop correlations between disperse dye structures and SC-CO2 solubility.
