How do you make formic anhydride?
Acetic formic anhydride can be prepared rapidly in situ by stirring formic acid, acetyl chloride, and Triethylamine in THF at −70 °C for 10 min.
AFA is found in a mixture of formic acid (excess) with Acetic Anhydride ._{15 avr. 2001}
What is acetic formic anhydride used for?
Acetic formic anhydride is a useful intermediate for the formylation of amines,³^,⁷ amino acids,⁸^,⁹ and alcohols,²^,¹⁰ for the synthesis of aldehydes from Grignard reagents,¹¹ and for the preparation of formyl fluoride.
On an industrial scale acetic anhydride is currently produced either by reaction of ketene and acetic acid, the ketene being obtained either by dehydration of acetic acid or by decomposition of acetone, or by oxidation of acetaldehyde which also yields acetic acid.

Acetic formic anhydride can be produced by reacting sodium formate with acetyl chloride in anhydrous diethyl ether between 23–27 °C. It can also be prepared by the reaction of acetic anhydride and formic acid at 0 °C.
