Oxidation of 9-decen-1-ol (rosalva) by air in aqueous media on platinum catalysts

Abstract

Oxidation of 9-decen-1-ol to 9-decenoic acid was conducted in aqueous media (dioxane–water mixtures) in the presence of supported palladium or platinum catalysts. The beneficial effect on the activity of a bismuth promoter, deposited on the platinum particles by a redox reaction, was demonstrated. Operating in a mass-transport-limited regime improves the resistance of the catalyst to deactivation by over-oxidation. Oxydation du dec-9-en-1-ol (rosalva) par l'air en milieu aqueux sur des catalyseurs au platine. L'oxydation du dec-9-en-1-ol en acide dec-9-en-1-oïque a e′te′ effectue′e en mileu aqueux (me′langes dioxane–eau) en pre′sence de catalyseurs au palladium ou platine supporte′s. Un effet promoteur sur l'activite′ du bismuth de′pose′ sur les particules de platine par une re′action redox a e′te′ de′montre′. Le fait d'ope′rer en re′gime limite′ par le transport de matière augmente la re′sistance du catalyseur à la de′sactivation par suroxydation.
