Abstract
L'invention concerne un procédé de production d'aldéhydes aromatiques en phase liquide. On prépare des aldéhydes aromatiques tels que le benzaldéhyde et des benzaldéhydes substitués par oxydation en phase liquide du toluène ou des toluènes substitués, en présence d'un catalyseur comprenant de l'acide phosphorisme et une quantité catalytiquement efficace de palladium métallique et d'un agent modificateur sulfuré, phosphoré ou azoté. Le procédé est particulièrement sélectif et permet d'obtenir des rendements élevés.
