Abstract

On décrit un procédé permettant de produire simultanément des acides monocarboxyliques aliphatiques et des acides aromatiques polycarboxyliques aliphatiques avec des taux élevés de sélectivité, conversion et production. L'acide monocarboxylique aliphatique peut servir dans le procédé comme un composant du solvant.
