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

Participants

Reaction Steps

459 g of 4-nitrophenylhydrazine was gradually added to 1.6 liters of acetonitrile, and then 322 g of formic acid was added to form a homogeneous solution, and, after 20 minutes, crystals formed. After allowing the reaction to proceed for 2 hours at a temperature of 80° C., 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. Melting point: 184° to 186° C.
