liquid-liquid distribution (extraction) (partition)
The process of transferring a dissolved substance from one liquid phase to another
(immiscible or partially miscible) liquid phase in contact with it. Although extraction
and distribution are not synonymous, extraction
may replace distribution where appropriate.
