Liquid Liquid Extraction: partition coefficient
Acetic acid Water 70 vol pct Tributylphosphate + 30 vol pct dodecane 20C to Acetic acid Water Methylisobutyl ketone 25C
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.
