Experiment: A mixture of equal proportions of benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene are to be separated by extraction using the solvent diethyl ether. Day 1: Part A. Isolation of the basic component: In a small beaker, dissolve 3 g of the mixture (benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene) in 30 mL of diethyl ether and transfer the mixture to a 125- mL separatory funnel (see Fig. 1) using a little diethyl ether to complete the transfer. Add 10 mL...

The Separation of Three Organic Compounds by Acid, Base Reactions and Liquid, Liquid Extraction. Okay, so we had solid benzoic acid, ethyl 4- aminobenzoate, and 9-fluorenone all dissolved in diethyl ether. We separated the basic component by adding 3M HCl, we separated the acidic component by adding 3M NaOH. I don't understand what happens here. To isolate the acidic solution, we added 6 M NaOH and used the vacuum to recover the solid. To isolate the basic solution we added...

4. Describe how to separate a mixture of phenol, benzoic acid, and toluene using aqueous NaHCO3, aqueous NaOH, and ether. NaOH can separate the shenol and NaHCO3 can be used for benzoic acid because it dissolved in it. Toluene will be more difficult because it doesn't dissolve in noot or Nation, but the ether can be used for it.

Draw the reaction mechanism with chemical structures in the separation of naphthalene and benzoic acid by extraction. 1g of Naphthalene/benzoic acid mixture is dissolved in 15 mL dichloromethane, transferred to a separatory funnel where 10 mL 2.5M NaOH(aq) is added. Organic and Aqueous layers are separated, and 12M HCl(aq) is added to the aqueous layer while cooling, forming a precipitate, which is vacuum filtrated. Don't understand how to draw each chemical structure!

8A student is given a solution of 20 ml. of ether, which contains benzoic acid and benzocaine. The student uses 5% NaOH to separate the benzoic acid from the benzocaine benzocaine is expected to remain in the organic layer (ether layer). After drying the organic layer, and removing the diethyl ether using a rotavapor, the student finds no benzocaine in the RBF. The student performed the experiment exactly, and no equipment was malfunctioning mechanistic force to help explain!l The Where...

Let's assume you have a mixture of equal parts benzoic acid, sand and toluene that are intimately mixed together (the crude material is a mixture of solid and liquid). Propose a procedure to separate these three components using any of the chemicals commonly available (you've used all of the "common" chemicals in the lab by now) in the organic chemistry teaching laboratories and observing the typical limitations with the instruments and techniques (such as not being able to distill or...

An unknown mixture (dissolved in diethyl ether) contains only 2 of the following : benzoic acid, phenol, aniline and napthalene. You use the acid-base extraction method and want to identify the 2 compounds in your original mixture. 1) To separate the organic acid you add NaOH and to separate the organic base you add HCl.In both cases these extractions are followed by extractions with water. Why do we add water? Why is this step important? (A clear explanation please). 2)When...
