Bicyclic phosphine enhaltender hydroformylation catalyst, and its use in the production of oxygenates

摘要

A process for producing oxygenated products from an olefinic feedstock, which process includes reacting, in a hydroformylation reaction stage, an olefin feedstock with carbon monoxide and hydrogen at elevated temperature and superatmospheric pressure in the presence of a hydroformylation catalyst. The hydroformylation catalyst comprises a mixture of a metal, M, where M is cobalt (Co), rhodium (Rh), ruthenium (Ru) or palladium (Pd); carbon monoxide; and a bicyclic tertiary phosphine having a ligating phosphorus atom. The ligating phosphorus atom is neither in a bridgehead position nor a member of a bridge linkage. The process produces oxygenated products comprising aldehydes and/or alcohols.
