Abstract
The Abraham general solvation model is used to calculate the numerical values of the solute descriptors for benzil from experimental solubilities in organic solvents. The mathematical correlations take the form
where C S and C W refer to the solute solubility in the organic solvent and water, respectively, C G is a gas-phase concentration, C 2 is the solute excess molar refraction, V x is the McGowan volume of the solute, \(\sum {\alpha _2^{H}}\) and \(\sum {\beta _2^{H}}\) are measures of the solute hydrogen-bond acidity and basicity, \({\pi }_{2}^{H}\) denotes the solute dipolarity/polarizability descriptor, and L [16] is the solute gas-phase dimensionless Ostwald partition coefficient into hexadecane at 25°C. The remaining symbols in the above expressions are known solvent coefficients, which have been determined previously for a large number of gas/solvent and water/solvent systems. We estimate R 2 as 14.45 cm3-mol−1 and calculate V x as 163.74 cm3-mol−1, and then solve a total of 51 equations to yield \({\pi }_{2}^{H}\) = 1.59, \(\sum {\beta _2^{H}}\) = 0.620 and log L [16] = 7.6112. These descriptors reproduce the 51 observed log(C S/C W) and log(C S/C G) values with a standard deviation of only 0.115 log units.
