Solubility of phenanthrene in organic nonelectrolyte solvents. Comparison of observed versus predicted values based upon Mobile Order theory

摘要

Experimental solubilities are reported at 25.0degCfor phenanthrene dissolved in 41different organic nonelectrolytesolvents containing ether, carbonyl, hydroxy, chloro, amino, ester,methyl and tert-butyl functional groups. Results of thesemeasurements are used to test the applications and limitations ofexpressions derived from Mobile Order theory. For the 31 solventsfor which predictions could be made, computations show thatMobile Order theory does provide fairly reasonable estimates ofthe saturation mole fraction solubilities. Average absolutedeviation between predicted and observed values is 41.3percent(excluding acetonitrile). In comparison, the average sbsolutedeviation is 1610percent when ideal solution behavior is assumed.Also reported are experimental solubilities at 26degC for pyrenedissolved in 1-hexanol, 1-heptanol, ethylbenzene, aniline, and 2-butanone.
