| titleOfInvention | Protocatechualdehyde production method |
| abstract | An object of the present invention is to provide a high-yield and simple method for producing protocatechualdehyde which has improved agitation during the reaction and does not use toxic chlorine gas. The object of the present invention is to provide a piperonal represented by the following formula (1) in an organic solvent in the presence of oxygen and After the reaction with phosphorus pentachloride, water is added to the obtained reaction solution to further react, and the solution is solved by a method for producing protocatechualdehyde represented by the following formula (2).
