The yields of the transacylation products, phthalic anhydride and acetanilides, are increased in the presence of acetic acid or high amic acid concentration and are decreased by the presence of sodium acetate. The rate of the reactions of the N-arylphthalamic acids increases with increasing acetic...

The acylation can expediently, in particular if a mixed anhydride of the acids of Formula II with a sulfonic acid is used as acylation agent, be carried out in the presence of an acid-binding reagent. Suitable acid-binding agents are for example organic bases which are soluble in the reactio...
