The Abraham solvation parameter model is used to predict the experimental solubilities of fluorene in organic solvents, from the correlation equations, below, and already determined descriptors for fluorene. The mathematical correlations take the form ofwhere C s and C w refer to the solute solubility in the organic solvent and water, respectively, C G is a gas phase concentration, E is the solute excess molar refraction, V is McGowan volume of the solute, A and B are measures of the solute hydrogen-bond acidity and hydrogen-bond basicity, S denotes the solute dipolarity/polarizability descriptor, and 313 314 D. M. Stovall et al.L is the logarithm of the solute gas phase dimensionless Ostwald partition coefficient into hexadecane at 298 K. 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. The Abraham solvation parameter model was found to predict the experimental solubility data and published gas chromatographic retention data of fluorene to within an overall standard deviation of 0.109 log units.

“…The descriptors for methyl naphthalenes are in Table 3, and the final correlation equations for the GLC retention data, eqns. ( 4)-( 9), 1,[9][10][11] and the HPLC retention indices, eqn. ( 10), 1 are as follows.…”

“…The large difference in coefficients between the GLC equations arises from the fact that some of the GLC retention data refer to alkanes as standards, eqns. ( 4)-( 6), 1,9 and some refer to polyaromatic hydrocarbons as standards, eqns. ( 7)-( 9).…”

The GLC and HPLC data of Autenrieth and co-workers (P. Dimitriou-Christidis, B. C. Harris, T. J. McDonald, E. Reese and R. L. Autenrieth, Chemosphere, 2003, 52, 869) has been used to obtain solvation descriptors for methyl naphthalenes for use in the Abraham solvation equations. These descriptors are then used to predict a large number of physicochemical properties, of environmental importance. These include solubility in water and the gas-water partition coefficient (equivalent to the Henry's Law constant for the water to gas partition). Predictions are in excellent agreement with those of Autenrieth and co-workers and with experimental observations, where available. Other important predictions are the gas-dry octanol and gas-wet octanol partition coefficients. Descriptors have also been obtained for the ethyl-, propyl- and butyl-naphthalenes which, again, can be used to predict numerous physicochemical properties.

“…Undoubtedly the major attributes of HRGC are its ability to separate complex mixtures, its speed in performing separations, and its ability to obtain analytical quantitat.ions for separated constituents. Gas chromatography can also supply qualitative data by using the Kovats retention index system [60,61] for identifying the various emerging solute zones. This system is widely used for isothermal Chromatographie determinations [62] .…”
