| titleOfInvention | Method for producing 3-cyanobenzaldehyde |
| abstract | (57) [Summary] [Objective] 3-Cyanobenzaldehyde is obtained in high yield from easily available raw materials by a simple operation. [Structure] Isophthalaldehyde is reacted with hydroxylamine in the presence of formic acid and / or acid anhydride. Acetic anhydride or the like is used as the acid anhydride. Particularly preferably, the raw material components are reacted in the presence of formic acid and acetic anhydride. After reacting under reflux for several hours, water is added to obtain highly pure crystals of 3-cyanobenzaldehyde in high yield. |
