Abstract
Hydroformylation process, wherein an olefinic compound is reacted with hydrogen and carbon dioxide in the presence of a Group VIII precious metal complex catalyst containing an organic phosphorus compound as a ligand, the process being characterized by use of trialkyl phosphine, as the organic phosphorus compound, having the total carbon atom number of 27 or more in its alkyl groups.
Claims22
A hydroformylation process, comprising:
- reacting an olefinic compound with hydrogen and carbon monoxide in the presence of a catalyst of a rhodium complex containing having three identical alkyl groups, wherein the total carbon atom content in the alkyl groups of said trialkylphosphine is 27 or more.
A hydroformylation process, comprising:
- reacting an olefinic hydrocarbon or a substituted olefin with hydrogen and carbon monoxide in the presence of a catalyst containing a rhodium complex and a trialkylphosphine having three identical alkyl groups, wherein the total carbon atom content in the alkyl groups of said trialkylphosphine is 27 or more optionally in a solvent.
