A very typical extraction flow diagram is shown below, where a reaction mixture is quenched with water, extracted (several times), washed with brine, dried, filtered and finally evaporated to yield a crude product or a pure …
Extraction #1. Perform a single extraction using approximately (25 : text{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. There is no need ...
An acid-base extraction can be used to extract carboxylic acids from the organic layer into the aqueous layer. As was discussed in the previous section, (ce{NaOH}) can be used to …

Two Base Extraction Introduction : Given a 2 gram sample of a mixture containing benzoic acid, 2-naphthol, and naphthalene, we are to separate each part. Procedure : 1. The mixture is dissolved in 30 ml of diethyl ether. 2. 20 ml of 10% Bicarbonate is added to the solution in a separatory funnel where the aqueous
The following flow chart shows the general procedure for isolating the three compounds (benzoic acid, 2-naphthol, and naphthalene) out of the unkn own mixture using their solubility and that of their salts.
This flow chart should provide a clear outline of all the steps in the process and should therefore enable you to follow the experiment more easily.
For flow chart, use "N" for neutral, "RCO 2H" for protonated carboxylic acid, "RCO 2-" for ionic carboxylate salt, "RNH 2" for neutral amine, and "RNH 3 +" for ionic ammonium salt. Part 1: …
An acid-base extraction can be used to extract carboxylic acids from the organic layer into the aqueous layer. As was discussed in the previous section, (ce{NaOH}) can be used to convert a carboxylic acid into its more water-soluble ionic carboxylate form.

For flow chart, use "N" for neutral, "RCO 2H" for protonated carboxylic acid, "RCO 2-" for ionic carboxylate salt, "RNH 2" for neutral amine, and "RNH 3 +" for ionic ammonium salt. Part 1: Separation of a Neutral from a Carboxylic Acid. Setup: 1. Attach your small metal ring to one of the vertical rods on your rack 2.
Figure 6 details a full acid/base extraction flow chart that describes the separation of a mixture of an organic acid (HA), organic base (B:) and a neutral organic molecule (N). naphthalene

At the end of a procedure to separate the components of a mixture, the neutral compound can be recovered in its solid form by evaporation of the organic solvent. The flow chart on the next page outlines a general procedure for separating acidic, basic and neutral organic compounds using the principles of the solubility switch.
