Abstract

Procédé de production d'alcools et/ou d'aldéhydes selon lequel on soumet un dérivé de toluène possédant une ou plusieurs liaisons éther à une auto-oxydation en phase liquide avec de l'oxygène moléculaire, la réaction d'auto-oxydation étant efféctuée en utilisant un acide gras saturé inférieur et/ou un anhydride de ce dernier comme solvant en présence d'un sel de cobalt soluble et d'une substance fournissant des ions brome, à 30-200 degrés C, si bien que le taux de conversion du produit de départ n'excède pas 90 %.
