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

Experimental solubilities are reported at 25.0°C for biphenyl dissolved in 26 different alkane, dialkyl ether, and alcohol solvents. Results of these measurements, combined with previously published biphenyl solubility data, are used to test the applications and limitations of expressions derived from Mobile Order theory. For the 40 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 13.0%.Key words: biphenyl solubilities, organic nonelectrolyte solvents, solubility predictions.
