Zusammenfassung:	PURPOSE:To manufacture terephthalaldehyde in a high yield by electrolytically oxidizing p-tolualdehyde dialkylacetal in a lower aliphatic alcohol having a specified number of carbon atoms in the presence of a supporting electrolyte and by carrying out hydrolysis. CONSTITUTION:P-tolualdehyde dialkylacetal is dissolved in a 1-4C lower aliphatic alcohol such as methanol or ethanol as a solvent to 0.05-0.5mol/l concn. The solvent may be mixed with
