METHOD FOR PRODUCING AROMATIC CARBOXYLIC ACIDS

摘要

PROBLEM TO BE SOLVED: To provide a method for producing aromatic carboxylic acids by industrially advantageous method when producing the corresponding aromatic carboxylic acids by oxidizing alkyl-substituted aromatic aldehydes. SOLUTION: Aromatic aldehydes are brought into contact with molecular oxygen in a self-solvent or an organic solvent in the presence of a metal catalyst and a basic compound.
