Preparation: Benzoic anhydride is mainly produced by the carbonylation of methyl acetate. Maleic anhydride is produced by the oxidation of benzene or butane. Laboratory routes emphasize the dehydration of the corresponding acids. The conditions vary from acid to acid, but phosphorus pentoxide is a common dehydrating agent:
2 CH₃COOH + P₄O₁₀ → CH₃C(O)OC(O)CH₃ + "(HO)₂P₄O₉"

Uses of Benzoic anhydride: it can be used to produce furan-2-yl-phenyl-methanone by heating. This reaction is a kind of Friedel-Crafts acylation. It will need  solvent CH₂Cl₂. The yield is about 80%.
