Separatory funnel extraction

A separatory funnel (see picture) is used for this process. In this procedure, the organic product is isolated from inorganic substances. Into the separatory funnel pour the liquid to be extracted using a funnel: this prevents liquid from getting on the ground glass joint which can cause it to stick. Pour the extractive solvent into the funnel. Hold the separatory funnel so that your fingers firmly cover the stopper. … Extraction. Liquid-liquid extractions using a separatory funnel are essentially the only kind of extraction performed in the organic teaching labs.

This document outlines the procedure for isolating water-insoluble and slightly soluble organic compounds from aqueous samples in preparation for a variety of chromatographic procedures. You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more. PROCEDURE FOR EXTRACTION Add the extraction solvents to the separatory funnel (be certain the Teflon stopcock is closed first!).

Separation of Aldehydes and Reactive Ketones from Mixtures

Extractions are performed in a separatory funnel. When two immiscible liquids are placed in the separatory funnel two phases are observed as discussed above. As mentioned before, the fundamental reason for carrying out an extraction is to isolate a compound from a mixture. The Soxlet extraction method uses the same three choices of solvent as for the partition-gravimetric method: n-hexane, MTBE, or an 80/20 v/v mixture of the two. The extraction procedure, however, is carried out in a reflux apparatus as opposed to a separatory funnel.
