Solubility of hexachlorobenzene in organic nonelectrolyte solvents. Comparison of observed vs. predicted values based upon Mobile Order model

Experimental solubilities are reported at 25.0 degrees C for hexachlorobenz ene dissolved in 42 different organic nonelectrolyte solvents containing et her-, chloro-, hydroxy-, ester, methyl-, and tert-butyl-functional groups. Results of these measurements are used to test the applications and limitat ions of expressions derived from Mobile Order model. For the 33 solvents fo r which predictions could be made computations show that Mobile Order model does provide fairly reasonable estimates of the saturation mole fraction s olubilities. Average absolute deviation between predicted and observed valu es is 210%. In comparison, the average absolute deviation is 2 060% when id eal solution behavior is assumed.
