The unconventional solution model of Mobile Order, which has previousl
y been shown to provide a very accurate thermodynamic description of a
nthracene and pyrene solubilities in binary hydrocarbon + alcohol and
alcohol + alcohol solvent mixtures, is extended to aqueous-alcohol sol
vent systems. An expression is derived for predicting the solubility o
f an inert crystalline solute in binary alcohol + water mixtures from
measured solubilities in both neat liquid solvents plus hydrogen-bondi
ng stability constants. Applications and limitations of the newly-deri
ved equation are assessed using published solubility for 4-chlorobiphe
nyl dissolved in binary methanol + water, ethanol + water and 1-propan
ol + water solvent mixtures.
