PURPOSE:To obtain hydroformylated compounds in a low concentration of rhodium at a moderate rate in a high yield by specifying the content of polyenes in the above-mentioned raw material and the amount of the above-mentioned catalyst used in hydroformylation of an unsaturated fatty acid compound in the presence of a rhodium catalyst. CONSTITUTION:In hydroformylation of a monounsaturated fatty acid compound (monoene compound) containing unsaturated fatty acid compounds (polyene compound) having >=2 carbon-carbon double bonds in the molecule by reaction with hydrogen and carbon monooxide in the presence of a rhodium catalyst, the above-mentioned polyene compounds are used in an amount of <=6.0wt.%, preferably 0.005-5.5wt.% based on the total amount of the monoene and polyene compounds and the above-mentioned catalyst is used in an amount of (1.4X10<-5>)-(1.9X10<-2>)wt.%, preferably (1.4X10<-4>)-(1.7X10<-2>)wt.% as a converted value into rhodium atom based on the total amount of the monoene and the polyene compounds to produce the objective hydroformylated compounds at a moderate rate in a very high yield in such a low-rhodium concentration that the condition is industrially advantageous. |
