Abstract
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.
Claims14
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 comprising a mixture or combination 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 and being a [3.3.1]phosphabicyclononane represented by formula (III):
- 4
- where R1 is an alkyl, branched alkyl, cycloalkyl, or aryl group;
- R2 is an alkyl group;
- and
- R3 is an alkyl group, to produce oxygenated products comprising aldehydes and/or alcohols:
A hydroformylation catalyst which includes, as a first component, a metal M, where M is cobalt, rhodium, ruthenium, or palladium;
- as a second component, carbon monoxide;
- and, as a third component, a bicyclic tertiary phosphine having a ligating phosphorus atom and being a [3.3.1]phosphabicyclononane represented by formula (III):
- 5
- where R1 is an alkyl, branched alkyl, cycloalkyl, or aryl group;
- R2 is an alkyl group;
- and
- R3 is an alkyl group, with the components being in the form of a mixture.
