Description

The solvent extraction of a substance is a simple liquid-liquid extraction. In this case the extraction material is shaken with the extraction agent in a closed vessel, the separatory funnel. The liquids must not be miscible! The substance to be extracted goes over to the extraction agent. In experiment C2.4.2.2 this technique is illustrated by the solvent extraction of a leaf extract with oil.
