2.3: LIQUID-LIQUID EXTRACTION

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 product.

Flow Chart of Procedures for Experiment #1: Two Base …

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

Liquid/liquid Extraction 30 LIQUID/LIQUID …

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.

Exp 6

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

4.6: Step-by-Step Procedures For Extractions

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 ...

4.8: Acid-Base Extraction

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.

Experiment 3: Extraction: Separation of an Acidic, a …

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.
