Abstract: The widespread use of liquid-liquid distribution, ranging from analytical chemical technique to a unit operation in various fields of chemical technology (e.g. petroleum refining, nuclear fuel reprocessing, hydrometallurgy, food technology, biochemistry) has led to a proliferation of terminology. This paper extends the scope of the definitions beyond those previously recommended (Pure Appl. Chem. 1970, 21, 111-113) and a list of terms, including those previously published, is presented under the following general headings: general definitions of phenomena, operations and relationships; components of the solvent phase; fundamental parameters for quantitative description of liquid-liquid distributions systems; process terminology applicable to large scale continuous operations.
