SOLUBILITY OF ANTHRACENE IN COMPLEX SOLVENT SYSTEMS

The solubility of anthracene was measured in binary and ternary cosolvent-water systems. The binary systems consisted of water and a completely miscible organic solvent (CMOS); while, the ternary systems incorporated a partially miscible organic solvent (PMOS) into the binary systems. A model is developed which predicts that the incorporation of a PMOS, as a solubilized solute, into a CMOS-water mixture can lead to an increase in the solubility of anthracene due to cosolvency effect of the PMOS. The results indicate a good correlation between the observed vs. predicted increase in solubility. © 1991, Taylor & Francis Group, LLC. All rights reserved.
