Abstract: Provided is a first process of producing an anhydride of an organic mono-acid comprising performing a transanhydridization reaction of an organic mono-acid and a thermally regenerable anhydride to produce the anhydride of the organic mono-acid and an acid of the thermally regenerable anhydride, wherein at least one of the organic mono-acid and thermally regenerable anhydride is provided by a preprocess that is integrated with the first process. An anhydride production system that is integrated with at least one preprocess, a wood acetylation process coupled to an acetic anhydride production process, a process of supplying an acetic acid reactant feed to a transanhydridization reaction unit, and an integrated wood acetylation and anhydride production system also are provided.

Abstract: Provided is a method of producing an anhydride of an organic mono-acid comprising contacting an organic mono-acid and a thermally regenerable anhydride to produce the anhydride of the organic mono-acid, and either a diacid of the regenerable anhydride, a partially hydrolyzed regenerable anhydride, or both. In a particular example, acetic acid and glutaric anhydride can be reacted to form acetic anhydride.
