Summary
The accumulation of activity coefficients of model hydrocarbon solutes at infinite dilution in a wide range of solvents has led to a generalized correlation pattern of hydrocarbon solution behavior which should find increasing application in the interpretation and prediction of the results from solvent extraction or liquid-liquid partition chromatography. The pattern allows characterization of solvent environments for essentially any hydrocarbon solute in terms of five experimental infinite dilution activity coefficients. In principle, such characterization allows the independent pairing of any of these environments to give at least a hypothetical picture of how hydrocarbon solutes would be expected to distribute if the two environments were in fact in phase equilibrium. The independent choosing of solvent pairs can set up situations which allow maximum separation according to molecular weight of the solutes or maximum separation according to the types of solutes. It is believed the improved quantitative understanding of the factors involved in the extraction of broad fractions should be of considerable value in carrying out analytical separations of such oil fractions for either gaining direct information or the preparing of cuts for subsequent, more definitive analysis.
