Thus, (CH 3 CO) 2 O is called acetic anhydride. Mixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known. One or both acyl groups of an acid anhydride may also be derived from another type of organic acid, such as sulfonic acid or a phosphonic acid.ixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known.

A molecule can have more than one acyl halide functional group. For example, adipoyl dichloride, usually simply called adipoyl chloride, has two acyl chloride functional groups; see the structure at right.It is the dichloride (i.e., double chloride) of the 6-carbon dicarboxylic acid adipic acid.n acyl halide (also known as an acid halide) is a chemical compound derived from an oxoacid by replacing a hydroxyl group with a halide group. If the acid is a carboxylic acid, the compound contains a âCOX functional group, which consists of a carbonyl group singly bonded to a halogen atom.
