Formic Acid → Formanilide

Participants

Reaction Steps

There are gradually added 58.8 parts by weight of formic acid (97%) to 113.0 parts by weight of aniline while maintaining a temperature of 90°±5° C. After completion of the addition, the mixture is heated at refluxing temperatures for about 25±5 minutes and finally heated to a pot temperature of 170°±5° C. The distillate collected consists of 27.0 parts by weight of water and a very small amount of formic acid (maximum 0.3 parts by weight). To the product in the pot, comprising 142.7 parts by weight of formanilide and 2.2±0.3 parts by weight of aniline, 75.0 parts by weight of xylene is added.
