The Abraham general solvation model is used to predict the saturation solubility of crystalline nonelectrolyte solutes in organic solvents. The derived equations take the form of log (CS/CW) = c + rR2 + sπ2H + aΣα2H + bΣβ2H + vVx and log (CS/CG) = c + rR2 + sπ2H + aΣα2H + bΣβ2H + l log L(16) where CS and CW refer to the solute solubility in the organic solvent and water, respectively, CG is a gas-phase concentration, R2 is the solute's excess molar refraction, Vx is McGowan volume of the solute, Σα2H and Σβ2H are measures of the solute's hydrogen-bond acidity and hydrogen-bond basicity, π2H denotes the solute's dipolarity and (or) polarizability descriptor, and log L(16) is the solute's gas-phase dimensionless Ostwald partition coefficient into hexadecane at 298 K. The remaining symbols in the above expressions are known equation coefficients, which have been determined previously for a large number of gas–solvent and water–solvent systems. Computations show that the Abraham general solvation model predicts the observed solubility behavior of anthracene, phenanthrene, and hexachlorobenzene to within an average absolute deviation of about ±35%.Key words: solubility predictions, organic solvents, nonelectrolyte solutes, partition coefficients.

Equilibrium Data

Experimental solubilities are reported for diphenyl sulfone dissolved in 8 alkane, 10 alcohol, and in aqueous solvent media at 25°C. Results of these measurements are used to test the predictive ability of the general solvation model log CA,orgsat/CA,aqsat = c + rR2 + sπ2H + aΣα2H + bΣβ2H + vVxwhere CA,orgsat and CA,aqsat refer to the solute solubility in the organic solvent and in water, respectively, R2 is the solute's excess molar refraction, Vx is the McGowan characteristic volume of the solute, π2H denotes the solute's dipolarity/ polarizability, and Σα2H and Σβ2H are the overall hydrogen-bond acidity and basicity descriptors for the solute. The remaining symbols in the above expression are known solvent coefficients, which have been determined previously through regressional analysis of published organic solvent - water partition coefficient and vapor-liquid equilibrium data. Computations show that the general solvation model predicts the solubility behavior of diphenyl sulfone in the 11 organic solvents for which predictions could be made to within an overall average absolute deviation of about ±20%. Key words: diphenyl sulfone solubilities, organic solvents, solubility predictions, general solvation model.

Important Challenge

The solvent-based exfoliation of graphite, including into graphene and/or graphene-like platelets, is an important challenge. Here, we report a “direct” Friedel-Crafts acylation reaction between graphite and 4-ethylbenzoic acid (EBA) to afford edge-functionalized graphite (EFG). Unlike, for example, graphite oxide (GO), the functionalization is at the edges of the graphite and thus, the basal plane of individual layers in EFG is not functionalized. The EFG can be easily dispersed and exfoliated in common organic solvents to concentrations as high as 0.8 mg/mL. Large-are uniform films can be produced by solution-casting such dispersions on substrates and conductivities as high as 125 S/cm can be obtained by subsequent heat treatment at 900 °C under argon atmosphere. Hence, a few layers graphene obtained from annealing under argon atmosphere show the potential to replace Indium tin oxide (ITO).
