Liquid–liquid extraction

Method to separate compounds or metal complexes
Abstract

Liquid–liquid extraction is a method to separate compounds based on their relative solubilities in two different immiscible liquids, often water and an appropriate organic solvent. During extraction process, there is a net transfer of one or more components between the two liquid phases. This partitioning of compounds allows for purification of reaction mixtures or transfer of desirable products to an organic phase that is more easily evaporated than water.
