摘要

The Solubility of disperse dyestuffs in supercritical carbon dioxide was measured using a modified UV-Visible spectroscopy. The disperse dyestuffs are C.I. Disperse Red (S type, mono-azoic), and C.I. Disperse Yellow (E type, quinoline). The concentrations were determined in the temperature and pressure ranging from 333.15 K to 393.15 K and 146 atm to 308 atm. We confirmed the possibility of an in situ experimental apparatus for measuring solubilities of disperse dyestuffs in SCCO2.
