Abstract:
The invention relates to a method for producing at least one alkoxy-hydroxybenzaldehyde (AHBA) from at least one hydroxyphenol (HP), said method being characterized in that it comprises the formation of at least one alkoxyphenol (AP) and alkyl-alkoxyphenol (AAP) and the separation (S) of AP from AAP, said separation (S) being carried out prior to obtaining AHBA.
