1)ethyl -4-aminobenzoate + HCL followed by NaOH
2) adding dry MgSO4 to 1- Chlorobutane and toluene mixture
When we add a drying agent to the mixture water is out, then by distillation we can separate the two mixtures, what i want to know is how MgSO4 is removing the water from the solution.

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...

Separating ethyl-4-aminobenzoate, phenanthrene, and salicylic acid in a solution. Don't know the concentrations of any of them. Planning to use HCl to precipitate the salicylic acid out, but will have access to 6 M and 1 M and I'm not sure which to use. Then adding NaOH to organic layer to precipitate out the ethyl-4-aminobenzoate, but again I'm not sure what molarity to use between the 1 M and 6 M (we will have access to 1 M and 6...

Extraction of benzoic acid and 9-fluorenone using diethyl ether. (please do not include ethyl 4- aminobenzoate). I have to create a flow chart to diagram the key steps of the experiment and isolation of products. 0.100g of benzoic acid and 9-fluorenone are dissolved in diethyl ether. The extraction solvent is 5% sodium hydroxide (to extract the acidic component from the organic phase). Saturated sodium chloride is added to the organic layer. drying the organic solution: anhydrous sodium sulfate is added...

Okay, so we had solid benzoic acid, ethyl 4- aminobenzoate, and 9-fluorenone all dissolved in diethyl ether (4ml). 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 6M HCl. Here are the questions I am having trouble with... • Why...

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...
