Experimental solubilities are reported at 25.0°C for anthracene dissolved in twenty-one different organic nonelectrolyte solvents containing cyano-, ester-, ether-, chloro-, fluoro- and amide-functional groups. Results of these measurements, combined with previously published anthracene solubility data, are used to test the applications and limitations of expressions derived from Mobile Order theory. For the 44 solvents for which predictions could be made computations show that Mobile Order theory does provide fairly reasonable (although by no means perfect) estimates of the saturation mole fraction solubilities. Average absolute deviation between predicted and observed values is circa 31.0%, excluding acetonitrile. In comparison, the average absolute deviation increases significantly to 910% when ideal solution behavior is assumed.
