The partition of organic compounds from water into the methyl isobutyl ketone extraction solvent with updated Abraham model equation

NCJ Number
Date Published

In this study, experimental water-to-methyl isobutyl ketone partition coefficients were determined for 27 different organic solutes based on gas chromatographic measurements. 


Updated Abraham model correlations were determined for describing solute transfer into methyl isobutyl ketone by combining the measured partition coefficient data determined in the present study with published experimental values taken from chemical and engineering literature. A total of 119 compounds were used in determining the revised Abraham model correlations. After calculations, the revised mathematical correlations were found to match the experimental data to within an overall average standard deviation of 0.21 log units. (publisher abstract modified)
