Formic Acid → Hydrazinecarboxaldehyde, 2-(4-nitrophenyl)-

Participants

Reaction Steps

459 g of 4-nitrophenylhydrazine was added to 1.6 liters of acetonitrile, and then 322 g of formic acid was gradually added to form a homogeneous solution, and, after 20 minutes, crystals formed. After allowing the reaction to proceed for 2 hours at 80° C. of temperature in a reaction vessel, the reaction system was cooled and the crystals formed were recovered by filtration, washed with acetonitrile, and dried, to provide 493 g of 2-(4-nitrophenyl)-1-formylhydrazine.
