Fischer Esterification

Acetic Acid + Ethanol in the presence of Dowex, a solid catalyst. 4 samples were placed in 4 tubes, heated in a water bath.

Test tube 4 was left in the water bath overnight. When testing sample #4 with GC and NMR, one product was expected - the ester, ethyl acetate. However a small portion of acetic acid was present. I understand acetic acid is often used in excess (La Chat) but the ethanol was in equal ratio to the acetic acid, so should it not have appeared as well? I know its an equilibrium, but if one is present, wouldn't both acetic acid and ethanol be there if it had gone in reverse?

Good evening! I have synthetized benzocaine by Fischer esterification of para-aminobenzoic acid with ethanol and concentrated H2SO4 . Product was collected by vacuum filtration and tested for melting point. Results is 79-81 while literature value is 88-90. Also Yield was 59%. Could you please describe the way how this compound could be purified further (in detail please if it possible) Many thanks!

The mechanism for the Fischer esterification is shown on page 762 of your textbook. The acid catalyst is specifically used in twosteps – protonation of 10 to make 11 and in the formation of 13 (it is unlikely that 12 directly goes to 13 – there is probably a deprotonation of 12 then a reprotonation to make 13).Explain mechanistically what the purpose of these two protonations are.
