2. Separatory funnel - Wikipedia

   en.wikipedia.org/wiki/Separatory_funnel

   A separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities. [1]

3. Extraction (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Extraction_(chemistry)

   Laboratory-scale liquid-liquid extraction. Photograph of a separatory funnel in a laboratory scale extraction of 2 immiscible liquids: liquids are a diethyl ether upper phase, and a lower aqueous phase. Soxhlet extractor. Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution ...

4. Liquid–liquid extraction - Wikipedia

   en.wikipedia.org/wiki/Liquid–liquid_extraction

   A separatory funnel used for liquid–liquid extraction, as evident by the two immiscible liquids.. Liquid–liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar).

5. Countercurrent distribution - Wikipedia

   en.wikipedia.org/wiki/Countercurrent_distribution

   Countercurrent distribution, therefore, is a method of using a series of vessels (separatory funnels) to separate compounds by a sequence of liquid-liquid extraction operations. Contrary to liquid-liquid extraction, in the CCD instruments the upper phase is decanted from the lower phase once the phases have settled.

6. Acid–base extraction - Wikipedia

   en.wikipedia.org/wiki/Acid–base_extraction

   Acid–base extraction is a subclass of liquid–liquid extractions and involves the separation of chemical species from other acidic or basic compounds. [1] It is typically performed during the work-up step following a chemical synthesis to purify crude compounds [2] and results in the product being largely free of acidic or basic impurities.

7. Separation process - Wikipedia

   en.wikipedia.org/wiki/Separation_process

   A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity.

9. Filter funnel - Wikipedia

   en.wikipedia.org/wiki/Filter_funnel

   A filter funnel is a laboratory funnel used for separating solids from liquids via the laboratory process of filtering. [1] In order to achieve this, a cone-like shaped piece of filter paper is usually folded into a cone and placed within the funnel. The suspension of solid and liquid is then poured through the funnel.
