摘要：
Compressed liquid water at elevated temperatures is being evaluated as an extractive solvent for separating mixtures of oleochemicals. In this paper, results are presented for a model of the tall oil-water system, namely, the ternary system oleic acid-beta-sitosterol-water. A continuous-flow apparatus was used to measure liquid-liquid equilibrium compositions for this system at 572, 579, and 586 K. Selectivities of water for oleic acid relative to beta-sitosterol were found to be 10-15, and distribution coefficients of oleic acid ranged from 0.0063 to 0.048 for the temperatures investigated. The experimental data were correlated with the NRTL equation. Limited data are also presented for the oleic acid-dehydroabietic acid-water system.
