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.
