Liquid Liquid Extraction: partition coefficient
Aniline Water Heptane 25C to Butyric acid Water Methyl butyrate 30C
Liquid-liquid extraction design data from Perry's Section 15: partition coefficients K (wt% basis) for ~150 solute/solvent systems, Godfrey solvent miscibility numbers (polarity scale 1-31), interfacial tension by solvent class and in ternary systems, and extractor type selection data (features, production rates) for mixer-settlers, columns, and centrifugal extractors.
