A process is described for the purification of organometallic compounds or heteroatomic organic compounds from oxygen, water and from the compounds deriving from the reaction of water and oxygen with the organometallic or heteroatomic compounds whose purification is sought, comprising the operation of contacting the organometallic or heteroatomic compound to be purified, in the liquid state or in form of vapor, pure or in a carrier gas, with a catalyst based on iron and manganese supported on zeolites, and optionally also with one or more gas sorber materials selected among hydrogenated getter alloys and palladium deposited on a porous support.
L'invention concerne un procédé destiné à la purification de composés organométalliques ou de composés organiques hétéroatomiques par élimination de l'oxygène, de l'eau et des composés issus de la réaction de l'eau et de l'oxygène avec les composés organométalliques ou hétéroatomiques dont la purification est recherchée. Ce procédé consiste à mettre le composé organométallique ou hétéroatomique à purifier, lequel est à l'état liquide ou sous forme de vapeur, pur ou dans un gaz vecteur, en contact avec un catalyseur à base de fer et de manganèse à support zéolitique, et éventuellement avec une ou plusieurs matières de sorption de gaz choisies parmi des alliages getter hydrogénés et du palladium déposés sur un support poreux.
