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 to the organic solution until solution is clear. rinse the drying agent with warm ether and repeat rinsing until a yellow color appears.
isolation of the neutral compound: place beaker in water bath to evaporate the diethyl ether. the remaining compound should be 9-fluorenone.
isolation of the organic acid from the organic base: add 6M hydrochloric acid to flask until benzoic acid starts to precipitate out. test with litmus paper until neutralized.

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...
Which is the least soluble in chloroform? Benzoic acid, 9-fluorenone, or ethyl 4-aminobenzoate?

Draw the products of the reaction of benzoic acid with NaOH (aq) and identify the conjugate acid and base in the products. Determine the direction of the equilibrium for this reaction and use pKa values to justify your answer. Is the organic product of this reaction water soluble? Why or why not? Using the chemicals provided, benzoic acid, Ethyl p-aminobenzoate, Fluorenone, Sodium Hydroxide, Hydrochloric Acid, Anhydrous Sodium Sulfate, Diethyl Ether , how might you convert this product back to the...
Given: 50mL of solution diethyl ether solution containing 1.00g each of benzoic acid, phenol and aniline,50 mL of sodium bicarbonate solution, 50 ml of sodium hydroxide solution, sodium sulfate and HCl. 1. Which layer in the separatory funnel (top or bottom layer) is the organic layer during an extraction process? 2. Given that sodium bicarbonate and sodium hydroxide solution are 5% by weight, what would be the volume of 1M HCl needed to be added for acidification to crystalize the...
Acidic compound: Ethyl 4 aminobenzoate Neutral compound: Fluorenone (12 points). Separation Scheme:_(5 points for the aqueous extract or layer and 7 points for the organic extract or layer). By drawing the actual structures of the neutral compound that you have identified and either the acidic or basic compound or impurity present in your mixture, write a separation scheme for this binary mixture. Draw the appropriate complete structures with the correnct number of unshared electrons and/ or charges if any during...

Write a small introduction in words and a conclusion for this lab report Experiment 9 Acid-Base Extraction Liquid-liquid extraction utilizes the contrast solubilities of solutes in two immiscible solvents the separation of a mixture. An extracting solvent can be reactive that changes the character of solute. Consider a mixture of organic acid, organic base, and neutral substance, for example, benzoic acid, aniline, biphenyl, nd phenol. They sodium benzoate. Sodium hydroxide changes phenol to sodium phenoxide. Hydrochloric acid changes aniline to...
