PROCEDURE FOR EXTRACTION Add the extraction solvents to the separatory funnel (be certain the Teflon stopcock is closed first!). Two phases Place the cap on the separatory funnel. Holding the cap and funnel securely, invert the separatory funnel. Vent the separatory funnel: with the funnel

What is a separatory funnel and what is its function? Separatory funnels can be used for liquid-liquid extractions. Two liquids that do dissolve well in each other can be separated using this funnel based on unequal densities.

In this video we show you how to perform an extraction properly with a separatory funnel!Music by audionautix.com The separatory funnel in the ring stand (left), and venting the funnel (right). How to Use a Separatory Funnel Operation of a separatory funnel is not difficult, but there are several potential pitfalls which must be avoided. The first order of business is to get the two liquid phases in the funnel. Make sure the stopcock is closed! Liquid-liquid extractions using a separatory funnel are essentially the only kind of extraction performed in the organic teaching labs.

Inspect your separatory funnel. The organic chem teaching labs have acquired several Extraction is a technique used to separate and/or purify compounds. Place the organic extract into the separatory funnel, and add 50 mL of 3M NaOH. Intensive vertical reciprocating quick solvent extraction shaking unit. The separatory funnel shaker is able to shake six samples in identical conditions for any Narration : 9. Separating Funnel. The separating funnel is used when organic compounds are extracted from an aqueous solution with organic solvent.

Figure 4 shows the extraction of a solute ( represented as black dots ) from a solution containing two solutes ( black and red dots ).

Figure 4: Liquid-liquid extraction using a separatory funnel. Figure 4 shows the extraction of a solute ( represented as black dots ) from a solution containing two solutes ( black and red dots ). The distribution coefficient ( also known as the partition coefficient ) is a constant used to describe the concentration of solute remaining in each phase.
