Draw a product separation scheme to summarize how your pure product can be isolated in the esterification reaction. Being by listing all the compounds that could be mixed in with your product (reactants, solvents, and other products) and in each separation step include the solvent(s)/reagent and separation technique, phases/states of matter.

List of products, reactants, and other compounds involved

Reactants: isopropanol, acetic acid

Product that needs to be isolated: isopropyl acetate

other compounds: sulfuric acid, water, diethyl ether, 5% aqueous sodium bicarbonate, drying agent anhydrous sodium sulfate

I am having great difficulty with the calculations! Please help! I am needing limiting reagent, moles of limiting reagent, moles of methyl benzoate isolated, theoretical yield in moles and grams and percent yield! The procedure is for Methyl Benzoate by Fischer Esterification, it is the following:

1. Place 10.0 g of benzoic acid and 25 mL of methanol in a 100-mL round bottomed flask. In the fume hood, pour 3 mL of concentrated sulfuric acid slowly and carefully down the walls of the flask, and then swirl to mix the components.

2. Attach a reflux condenser, add a boiling stone, and reflux the mixture gently for 1 hour.

3. Cool the solution and decant into a separatory funnel containing 50 mL of water, and rinse the flask with 35 mL of diethyl ether. Add this ether to the separatory funnel, shake thoroughly, and drain off the water layer, which contains the sulfuric acid and the bulk of unreacted methanol.

4. Wash the ether in the separatory funnel with 25 mL of water followed by 25 mL of 5% sodium bicarbonate to remove any remaining traces of sulfuric acid and unreacted benzoic acid. Again shake, with frequent release of pressure by inverting the separatory funnel and opening the stopcock, until no further reaction is apparent; then drain off the bicarbonate layer into a beaker. If this aqueous material is made strongly acidic with hydrochloric acid, unreacted benzoic acid may be observed.

5. Wash the ether layer in the separatory funnel with saturated sodium chloride solution and dry the solution over anhydrous magnesium sulfate so that it no longer clumps together on the bottom of the flask. After 10 minutes, decant the dry ether solution into a flask, wash the drying agent with an additional 5 mL of ether, and decant again. Remove the ether using the rotary evaporator.
