摘要：

This paper presents a method of predicting partition coefficients for components of hydrocarbon mixtures with cosolvents in contact with water. It is shown theoretically that the hydrocarbon partition coefficients correlate with the water-phase cosolvent concentration. The cosolvent concentration in the water phase can in turn be estimated from experimental data or predicted with the aid of the UNIQUAC activity coefficient correlation. The method is confirmed by comparison with literature data for mixtures containing benzene, n-hexane, and cyclohexane with cosolvents ethanol and methanol. The results are useful for transport and fate studies for hydrocarbon spills. © 1990, American Chemical Society. All rights reserved.
