acid anhydride plus alcohol
Do acid anhydrides react with alcohol?
Reactions of Acid Anhydrides
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.Remarkably, highly efficient phosphoric acid (1-3 mol %)-catalyzed acylation of alcohols with acid anhydrides was achieved and a 23 g scale synthesis of an ester was demonstrated.
Also, phosphoric acid catalyst was effective for synthetically useful esterification from carboxylic acids, alcohols, and acid anhydride.
What happens if alcohol reacts with acid?
The reaction, called Fischer esterification, is characterized by the combining of an alcohol and an acid (with acid catalysis) to yield an ester plus water.
Under appropriate conditions, inorganic acids also react with alcohols to form esters.
What happens when you add alcohol to carboxylic acid?
When primary alcohol is treated with a carboxylic acid in the presence of sulphuric acid a compound is formed.
This compound has a sweet smell.
The compound obtained is called ester.
The chemical reaction occurring in the formation of the ester is known as an esterification reaction.
