Preparation of isoamyl acetate lab

22 ml of isoamyl acetate and 30 ml of glacial acetic acid ans 2ml of concentrated sulfuric acid

once cooled add 100 ml of cold water, separate layer. wash ester with 30 ml of saturated aqueous sodium bicarbonate

add 15 ml of water and 15 ml of brine to ester. Then place ester layer into 50 ml erlenmeyer flask and add about 3 grams of anhydrous magnesium sulfate. Then distill

question:

Look up the densitites and formula weights for isoamyl alcohol, isoamyl acetate, and acetic acid. Determin the limiting reagent and theoretical yield for this experiment in grams of isoamyl acetate. Show calculations.

Synthesis of Isoamyl Acetate

Acetic acid + isoamyl alcohol --*--> isoamyl acetate + water

*Sulfuric acid was used as the catalyst

1) a. Assuming that the reaction had gone to completion after the 20 minutes of refluxing, what compound(s) besides the desired product, isoamyl acetate, would be in the reaction flask?

b. Explain, using balanced chemical equations wherever possible and incorporating structural formulae, how you removed each of these compounds (answer to question 1a.) from the reaction mixture during the isolation/purification of the product, isoamyl acetate.

2) If this reaction between the acetic acid and isoamyl alcohol could only obtain a maximum yield of 67% of the desired ester, if you needed to produce 45 grams of isoamyl acetate, what are the minimum weights of both the acetic acid and isoamyl alcohol that you would need to measure out for this experiment? Show calculations.

3) Using structural formulae, give balanced equations to illustrate how you could synthesize the following esters, using the same type of reaction that was utilized in this experiment:

(i) Phenyl cyclopropylmethanoate

(ii) 2-pentyl propanoate

(iii) benzyl butanoate

Thank you!

I have a question about this 13C NMR spectrum. I am not sure if there are 6 or 7 peaks because the resolution is so low. Would this NMR be for Isoamyl Acetate? If so, which peaks correspond to which carbon environments?
