Olefinically unsaturated compounds are continuously hydroformylated under from 2 to 30 bar and at from 80 DEG to 130 DEG C. using, as a catalyst, a rhodium complex which contains, as ligands, sparingly volatile compounds of the general formula I <IMAGE> I where A is phosphorus, arsenic, antimony or bismuth and R1, R2 and R3 are each organic radicals, by a method in which the hydroformylation mixture consisting of liquid and gaseous components is removed from the reactor and is subjected to relatively high temperatures and/or relatively low pressures for a short time in a devolatilization column, the mixture at the same time being separated into a gas phase and a liquid phase, the gas phase is separated into the product and the recycle gas in a separator, and the recycle gas and the liquid phase from the devolatilization column are recycled to the reactor. |
