acid anhydride and alcohol reaction
What is the catalyst for acid anhydride alcohol?
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.Making esters using acid anhydrides
Taking ethanol reacting with ethanoic anhydride as a typical reaction involving an alcohol: There is a slow reaction at room temperature (or faster on warming).
There is no visible change in the colourless liquids, but a mixture of ethyl ethanoate and ethanoic acid is formed.
What happens when an acid reacts with an alcohol?
Esterification is the process of combining an organic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and water; or a chemical reaction resulting in the formation of at least one ester product.
What is the reaction of alcohol and acetic anhydride?
When acetic anhydride reacts with alcohol, it does not produce two molecules of ester, but an ester and ethanoic acid.
While ethanoic acid reacts with alcohol, it produces ester.
