Abstract
PURPOSE: To manufacture titled aldehyde or acetal in high yield compared with conventional methods, by electrolytically oxidizing p-acetoxytoluene in a solvent such as lower aliphatic alcohol in the presence of a specific supporting electrolyte.
CONSTITUTION: p-Acetoxytoluene is electrolytically oxidized in lower aliphatic alcohol such as methanol, or in a mixed solvent made by mixing ≤30vol/vol% lower aliphatic carboxylic acid e.g. acetic acid etc. with said alcohol in the presence of a supporting electrolyte having cationic part constituted of hydrogen, alkali metal, or substituted or unsubstituted ammonium group, and anionic group constituted of persulfuric acid, sulfonic acid, or fluoroboric acid, at 5W35°C (more preferably 5W15°C temp.), at 0.1W3 (more preferably 0.5W1.5) A/dm2 current density. Hereby titled aldehyde or acetal, which is useful as an intermediate for medicines, perfumes, is manufactured in high yield without causing environmental pollution.
