Abstract
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 be 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.
