Abstract (en)
1. A process for the preparation of a phthalaldehyde acetal of the general formula see diagramm : EP0164705,P4,F1 where R is alkyl of 1 to 4 carbon atoms, wherein an alkoxymethylbenzene of the general formula see diagramm : EP0164705,P4,F2 is electrolyzed in the presence of an alkanol of the formula ROH, where R has the above meaning, at a current density of from 0.1 to 20 A/dm**2 and at a temperature which is not less than 5 degrees C below the boiling point of the alkanol.
