Why is acetic anhydride used in synthesis?
If acetic anhydride is used instead of acetic acid, the reaction is much faster and has a higher yield (since acetic anhydride is much more reactive than acetic acid).
How is an ester formed from an acid anhydride?
Reacting an acid anhydride with an alcohol produces an ester and a carboxylic acid.
This is essentially the same reaction as with an acyl chloride (see Acyl Chlorides), but rather than releasing HCl, a carboxylic acid is formed.What is the ester formation of acetic anhydride?
The esterification of acetic anhydride by ethyl alcohol can be represented by the following balanced equation: (CH3CO)2O A+ C2H5OHB ⟶ CH3COOC2H5 + CH3COOH.
