Abstract
This invention relates to a catalyst system for the hydroformylation of propene consisting essentially of a catalytic complex of rhodium, carbon monoxide, and a triarylphosphine, and a cobalt compound; to the process for stabilizing and/or regenerating a catalyst complex combination of rhodium, carbon monoxide, and a triarylphosphine comprising adding a cobalt compound to said catalyst complex; and to the process of hydroformylating propene with said catalyst system.
Claims9
The process of stabilizing or regnerating the hydroformylation catalyst for propene, said catalyst consisting essentially of a catalytic complex of rhodium, carbon monoxide, and a triarylphosphine, comprising adding to said catalytic complex a cobalt compound free of any group which adversely affects the hydroformylation reaction.
In the process of hydroformylating propene with a catalytic complex consisting essentially of rhodium, carbon monoxide, and a triarylphosphine, the improvement comprising adding a cobalt compound to the reaction medium during the hydroformylation, said colbalt compound being free of any group which adversely affects the hydroformylation reaction.
