Solubility of diphenyl sulfone in organic nonelectrolyte solvents. Comparison of observed vs. predicted values based upon Mobile Order theory

摘要

Experimental solubilities are reported at 25.0deg C for diphenyl sulfone dissolved in 25 different organic nonelectrolyte solvents containing ether-, chloro-, hydroxy-, ester, methyl-, and tert-butyl-functional groups. Results of these measurements, combined with previously reported diphenyl sulfone solubilities taken from the chemical literature, are used to test the applications adn limitations of expressiosn derived from Mobile Order theory. For the 34 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 49.3%. In comparison, the average absolute deviation is 5 500% when ideal solution behavior is assumed.
