  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. Laboratory funnel - Wikipedia

    en.wikipedia.org/wiki/Laboratory_funnel

    Filter funnels have a neck of a thin capillary tube and ribs which increase the filter-papers' effectiveness and thus accelerate the process of filtering. [1] Powder funnels have a short and wide neck for fast pouring of powders. Separatory funnels are pear-shaped, have a cap and a short neck, with a stopcock for the even pouring of fluids ...

    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 ...

  5. 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.

  6. 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).

  7. 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.

  8. Work-up - Wikipedia

    en.wikipedia.org/wiki/Work-up

    A concentrated solution of sodium bicarbonate is added to the reaction mixture. This will promote the migration of impurities and byproducts to the aqueous layer and leave the product in the dichloromethane (organic layer). The aqueous and organic layers are allowed to separate. This process is typically performed in a separatory funnel.

  9. 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.
