Highlights

  • Published Abraham model eqns. found for 4 biphasic systems studied by Marlot et al

  • Authors’ and published Abraham model log P equationss differ greatly

  • Authors’ Abraham model eqn. does not describe experimental octanol/water data

Abstract

Abraham model correlations reported by Marlot and coworkers for the 1-octanol/water, 1-butanol/water, ethyl acetate/water, and heptane/methanol biphasic partitioning systems are compared to previously published Abraham model correlations. The previously published correlations for the fore-mentioned partitioning systems are based on more experimental data points, and exhibit much better descriptive ability as evidenced by much smaller standard deviations/standard errors and larger squared correlation coefficients.
