Abstract

Procédés dans lesqules du formaldéhyde, de l'acide formique ou des composé semblables sont oxydés en dioxyde de carbone et en eau par contact avec de l'oxygène en présence d'un métal noble catalytique déposé sur un support de carbone qui est protégé contre l'empoisonnement par les amines par un revetement d'unpolymère choisi parmi les polysiloxanes, les polypropylènes, les polyfluoroènes et les polyoxy-2,6-di-méthylphénylènes ayant une perméabilité adéquateà l'égard des réactants.
