Organic Chemistry: Separating Acids and Neutral Compounds by Solvent Extraction

Reagents and Solvents Used

Acetanilide/p-Toluic Acid mixture, diethyl ether, 3M hydrochloric acid, 0.5M sodium hydroxide, sodium sulfate, anhydrous, water-distilled or deionized

PURPOSE OF THE EXPERIMENT: Use solvent extraction techniques to separate a mixture consisting of a carboxylic acid and a neutral compound.

Questions:

1. What product would you obtain if you evaporated the water from the NaOH layer prior to acidifying the layer?

2. Suppose that you used dichloromethane instead of diethyl ether as the nonpolar solvent in this experiment. What changes in the procedure would you make in view of the fact that dichloromethane is more dense than water?

3. Benzoic acid (C6H5—COOH) is a weak acid and naphthalene is neutral, neither acidic or basic. Prepare a flowchart for the separation and recovery of benzoic acid and naphthalene.

Benzoic Acid: solubility in water: poor ; solubility in ether: good

Naphthalene: solubility in water: poor ; solubility in ether: good

Thank You In Advance!

You are trying to separate a mixture of the compound below. Label the compounds in order of expected elution from the alumina column (start with #1 as the compound you would elute first) Naphthalene

2-naphthol

Benzaldehyde

Benzoic Acid

Please detail the exact steps to separate a mixture of benzoic acid, phenol and anthracene. Please list all solvents, reagents and solutions needed to accomplish the separation. Thank you
