9) Glacial acetic acid is (as the name suggests) an acid. Why did you need the Nafion strip to perform the esterification reaction? a) The esterification is a base-catalyzed process. b) AcOH isn't a sufficiently strong acid to drive the equilibrium forward. c) AcOH is too strong an strong acid, and irreversibly reacts with the alcohol.

Dec 07, 2015 Distilling the solution to glacial acetic acid is therefore economically impractical. Ethyl acetate forms a positive azeotrope with water that boils at 70.4 C (with azeotropic composition 35.9% mole water and 64.1% mole ethyl acetate). By adding ethyl acetate as an entrainer, it is possible to boil off the azeotrope and obtain pure acetic ...
