摘要：

Specific-retention-volume data from gas-liquid chromatographic measurements can be used to obtain activity coefficients at infinite dilution. There are numerous such data in the analytical chemistry literature for a variety of binary systems containing common volatile organic fluids and high-boiling, multifunctional organic substrates. A data-reduction method has been established wherein chromatographic specific-retention-volume data may be used to estimate group-interaction parameters for the UNIFAC correlation to predict activity coefficients. New UNIFAC parameters are reported for 30 group interactions. © 1979, American Chemical Society. All rights reserved.
