A process 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 the purified in the liquid state or in form of vapor, pure or in a carrier gas, with a hydrogenated getter alloy, and optionally also with one or more gas sorber materials selected among palladium on porous supports and a mixture of iron and manganese supported on zeolites.
L'invention concerne un procédé de purification de composés organométalliques ou de composés organiques hétéroatomiques à partir de l'oxygène, de l'eau et des composés dérivés de la réaction de l'eau et de l'oxygène avec les composés organométalliques ou hétéroatomiques dont on recherche la purification. Ce procédé consiste à mettre en contact le composé organométallique ou hétéroatomique à purifier, à l'état liquide ou sous forme de vapeur, pur ou dans un gaz vecteur, avec un alliage dégazeur hydrogéné, et éventuellement avec un ou plusieurs matériaux sorbants de gaz choisis parmi le palladium sur des supports poreux et un mélange de fer et de manganèse sur des zéolites.
