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...

A mixture of compounds containing dimethylamine, phenol, ammonia, and acetic acid is separated using liquid-liquid extraction as follows: Step 1: Concentrated HCl is added followed by draining the aqueous layer. Step 2: Dilute NaOH is added to the organic layer followed by draining the aqueous layer. Step 3: Concentrated NaOH is added to the organic layer followed by draining the aqueous layer. Which compound would you expect to be extracted into the aqueous layer after the addition of dilute NaOH,...

Acid/Base Extraction
1. Provide a flow chart detailing the acid/base
extraction/separation of the compounds shown below. Your answer
must employ the following reagents: methylene chloride,
hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M),
10% sodium bicarbonate (aq). Clearly indicate the product(s) and
layers formed following each step of your separation scheme.
IMPORTANT: p-cresol is soluble in sodium hydroxide solution but
insoluble in neutral water or sodium bicarbonate solution. 2-
ethylbenzoic acid is soluble in both sodium hydroxide and...

A mixture containing 1, 3, 5-trimcthoxybcnzcnc (A), phenol (B), aniline (C) and 1-naphthoic acid (D) was dissolved in dichloromethane. Next two extractions were performed first using HC1 then with NaOH. Which of the compounds could not be separated in this procedure. Explain and show the pertinent reaction equation/s. student wanted to separate a mixture of benzoic acid and aniline that were dissolved in ethanol. Could the student separate the two compounds using a base extraction (NaOH)? Explain
