Title:
PRODUCTION OF OXYGENATED PRODUCTS
Document Type and Number:
WIPO Patent Application WO2003068719
Kind Code:
A3
Abstract:
A process for producing oxygenated products includes reacting an olefin feedstock with carbon monoxide and hydrogen at an elevated reaction temperature and at a superatmospheric reaction pressure in the presence of a hydroformylation catalyst, to produce oxygenated products. The catalyst comprises a mixture of a metal, M, where M is cobalt (Co), rhodium (Rh), ruthenium (Ru) or palladium (Pd); carbon monoxide; hydrogen; and a bicyclic tertiary phosphine. The phosphine has two cyclic structures and a ligating phosphorus atom, with the ligating phosphorus forming part of the largest ring structure of the molecule, and with fewer than two hydrocarbon substituents being present on the carbon atoms of the cyclic structures of the molecule.
