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 p ressure range of 200-400 atm, at 50-100 degrees C. The results were combine d with relevant solubility data from previous studies, and were used to dev elop correlations between disperse dye structures and SC-CO2 solubility.
