WebEsters of acetic acid (i.e., alkyl acetates) can be prepared in a more efficient manner by using acetic anhydride (rather than acetic acid) as the non-alcohol reactant (eq 2). Like Fischer esterification, this reaction is catalyzed by acid, but unlike Fischer esterification, it is very fast and irreversible. In this experiment you will choose WebInexpensive phosphoric acid (H 3 PO 4) catalyzes a safe and simple acylation of alcohols with acid anhydrides.
