Formic Acid → HCID 14115790, compound

Participants

Reaction Steps

A mixture of 19.5 g (0.14 mole) of 4-fluorobenzamide, 29.2 g (0.14 mole) of phosphorus pentachloride and 175 ml of carbon tetrachloride was heated at 60°-70° for 30 min. or until the HCl gas evolution had nearly stopped. The reaction was cooled to 25°-30° and 6.7 g (0.14 mole) of 97% formic acid was added dropwise. Stirring was continued for another 60 min. before the precipitate was collected by filtration, washed with AR carbon tetrachloride and air-dried to give 20.4 g, m.p. softens 109°, melts 110°-112°.
