Preparation of acetic formic anhydride
Anhydrous formic acid (13.8 g., 0.3 mole), prepared from the 85% formic acid by refluxing with phthalic anhydride ( Pryanishnikov and Shakhova, J. Gen. Chem. (U. S. S. R.), 2, 81 (1932)) was treated with a stream of ketene gas (0.3 mole) freed from acetone vapors. The reaction product was distilled at 19 mm and 15 ml of formic acetic anhydride was collected at 33-33.5 °C.
