4: Extraction. Extraction refers to transference of compound (s) from a solid or liquid into a different solvent or phase. In the chemistry lab, it is most common to use liquid-liquid extraction, a process that occurs in a separatory funnel. A solution containing dissolved components is placed in the funnel and an immiscible solvent is added …

Techniques for extraction and isolation of natural products: a …
Solvent extraction is the most widely used method. The extraction of natural products progresses through the following stages: (1) the solvent penetrates into the solid matrix; (2) the solute dissolves in the solvents; (3) the solute is diffused out of the solid matrix; (4) the extracted solutes are collected.

Bakers use the extract of vanilla, almond, orange, lemon, and peppermint in their dishes, essences that have been extracted from plant materials using alcohol (Figure 4.1b). Figure 4.1: Examples of extraction: a) Tea, b) Baking extracts, c) Plant pigments extracted into water droplets after sprinklers hit a fallen leaf on the sidewalk.

funnel Discussion: Crystallization, purification, and isolation (may only be restricted to a solid) are insufficient ways to separate mixtures of compounds. Extraction is the recovery of a substance from a mixture by bringing it into contact with a solvent, which dissolves the desired material.

The aqueous phase can be extracted again, up to three times. The combined organic fractions are typically dried with a drying agent, 9 then filtered, and the solvent evaporated. 9 A classic problem is that a student either has very little product after extraction ( because of improper mixing of phases) or that the student requires a vast amount …
