Lab 3. extraction of a three component mixture. lucas bargmann. chem 345 section: 2 9 25 abstract. the technique of acid base extraction and liquid liquid extraction are used to separate a mixture of solid benzoic acid, ethyl 4 aminobenzoate, and 9 fluorenone. these compounds are examples of an organic acid, an organic base, and a neutral. Distribution of solute between phases lies far to the right in equation (2.1) and the resulting value of k d is large, indicating a high degree of extraction from phase a into phase b. conversely, if k d is small, less chemical x is transferred from phase a into phase b. if k d is equal to 1, equivalent con centrations exist in each phase. 2.1. Extraction #1. perform a single extraction using approximately 25ml 25 ml of diethyl ether (an exact amount is not necessary), as described previously, making sure to appropriately label each layer (e.g. "top organic layer" and "bottom aqueous layer"). extraction #2. return the aqueous layer to the separatory funnel.

The coffee flavor compounds are extracted from the grounds into the water to form coffee. this video will illustrate the principles of extraction, and demonstrate solid liquid extraction in the lab through the removal of organochloride residues from soil. extraction uses the property of solubility to transfer a solute from one phase to another. The product (about 0.1 ml of a pale yellow oil) should be in the tip of the extraction vessel. carefully remove the solids trap and the orange peel, making sure you keep the tube upright to avoid. loss of your product. dry the outside of the tube with a paper towel, weigh the tube, and determine.
