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.
write an equation to describe the reaction of an acid anhydride with each of the following: water, alcohol, ammonia, a primary or secondary amine, lithium aluminum hydride. identify the product formed when a given acid anhydride is reacted with any of the reagents listed in Objective 4, above.

An Acid anhydride can be defined as a non-metal oxide which forms an acidic solution when reacted with water. In organic chemistry , it is a functional group consisting of 2 acyl groups combined by an oxygen atom.
Acid chlorides react with carboxylic acids to form anhydrides as shown in the reaction below. Some cyclic anhydrides can be synthesized from the corresponding dicarboxylic acid with gentle heating. The example below shows the reaction of glutaric acid to form a cyclic anhydride.
31 Οκτ 2019 · It is formed when 1 equivalent of water is removed from two equivalents of an organic acid in a dehydration reaction. In inorganic chemistry it termed as an acidic oxide which reacts with water and form oxyacid or react with a base to form a salt.
Acid anhydrides are made from two carboxylic acid groups joined together. To form an acid anhydride, a water molecule is lost in a condensation reaction between two carboxylic acids. This is why acid anhydrides are called anhydride – lack of water.
