Abstract
A process for efficiently producing aryl formate and aromatic carboxylic acid from aldehyde, which comprises oxidizing an aromatic aldehyde with an oxygen-containing gas in the presence of a volatile solvent up to a reaction ratio of 40 to 70 mol % to convert the aromatic aldehyde to a peracid, adding a stabilizer, and allowing the remaining aromatic aldehyde and the aromatic peracid to react while the volatile solvent is distilled off.
