Solubility of fluoranthene in organic nonelectrolyte solvents. Comparison of observed versus predicted values based upon Mobile Order theory
Experimental solubilities are reported at 25.0°C for fluoranthene dissolved in 36 different organic nonelectrolyte solvents containing ester, ether, hydroxy, chloro, methyl, and tert-butyl functional groups. Results of these measurements are used to test the applications and limitations of expressions derived from Mobile Order theory. For the 28 solvents for which predictions could be made, computations show that Mobile Order theory does provide fairly reasonable estimates of the saturation mole fraction solubilities. Average absolute deviation between predicted and observed values is 53%. In comparison, the average absolute deviation is 1574% when ideal solution behavior is assumed.Key words: fluoranthene solubilities, organic nonelectrolyte solvents, solubility predictions.
