acid anhydride reaction with water
How do anhydrides react with water?
Although slower reacting than acid chlorides, anhydrides react with water to form carboxylic acids, with alcohols to form esters, and with amines to form amides. Anhydrides can also be reduced to 1 o alcohols by hydride reduction.
Are acid anhydrides and acyl chlorides similar?
This page looks at the reactions of acid anhydrides with water, alcohols and phenols (including the manufacture of aspirin). These reactions are all considered together because their chemistry is so similar. There is also a great similarity between acid anhydrides and acyl chlorides (acid chlorides) as far as these reactions are concerned.
