PROCESS FOR PRODUCING ALDEHYDES

摘要

A process is described for preparing aldehyde by hydroformylation of olefins, in which the olefins together with carbon monoxide, hydrogen and paraffins are introduced into a solution of rhodium carbonyl-triphenylphosphine complexes as catalyst and phosphines as solvent, the improvement wherein the gas stream entering the catalyst solution contains 5 to 30% by volume of paraffins with 1 to 5 carbon atoms.
