25 juil. 2019 2 Model esterification reaction using menthol acetic anhydride (Ac2O)
Connors and Albert recommend using acetic anhydride/-. DMAP as a reagent for the quantitiative determination of hydroxyl groups in alcohols and phenols.
The reaction mechanism first goes through a pre- equilibrium between DMAP and acetic anhydride forming the acetylpyridinium cation and the acetate.
