I am functioning on a laboratory assignment and also we will certainly be preparing isoamyl acetate this week. My concern is, Why is the reaction mixture extracted v sodium bicarbonate and sodium chloride solution?

I know that it will be one acid/base reaction and also I'm assuming the salt bicarbonate will certainly react v the mountain to kind carbonic acid, which I recognize decomposes into water and carbon dioxide. I'm not sure though the the function of salt chloride and also what happens to the acetic acid once it reacts v the salt bicarbonate. I understand it will shed the hydrogen yet what happens to the rest of the molecule?

Any aid is appreciated. Thanks!

Edit: title must say sodium chloride rather of HCl

The salt bicarbonate extraction is provided to eliminate the catalytic HCl and any overabundance acetic acid. After ~ neutralization that the acid through bicarbonate, the staying anions (Cl- and AcO-) will get in the aqueous phase.

The NaCl wash is concucted come extract as much water as feasible (from the vault extractions) the end of the necessary phase.

Thank you! I have actually ome much more question if friend don't mind. Sulfuric acid is the acid supplied to prepare the ester. What is the allude of adding HCl in addition to the salt bicarbonate?

I'm not certain though of the duty of HCl and what happens to the acetic acid

You're prepare isoamyl acetate i beg your pardon is one ester of isoamyl alcohol and acetic acid. If ns remember correctly, the OH team on isoamyl alcohol creates a water molecule through the acidic hydrogen in acetic acid, and also the rest develops the ester. I imagine the HCl is just a catalyst. I think sulfuric is more common, yet I'm certain HCl would occupational too.
