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.

L'invention concerne un procédé de production de produits oxygénés à partir d'une matière première d'alimentation oléfinique, lequel procédé consiste à faire réagir, dans une étape de réaction d'hydroformylation, une matière première d'alimentation oléfinique avec du monoxyde de carbone et de l'hydrogène, à une température élevée et à une pression superatmosphérique, en présence d'un catalyseur d'hydroformylation. Ce catalyseur d'hydroformylation comprend un mélange de métal, M, dans lequel M est cobalt (Co), rhodium (Rh), ruthénium (Ru) ou palladium (Pd), du monoxyde de carbone, ainsi qu'une phosphine tertiaire bicyclique possédant un atome de phosphore liant. Cet atome de phosphore liant n'est ni dans une position de tête de pont, ni un élément d'une liaison pontée. Ce procédé permet de produire des produits oxygénés comprenant des aldéhydes et/ou des alcools.
