of the DiscLosure: OLefinicaLLy unsaturated compounds are continuousLy hydroformyLated under from 2 to 30 bar and at from 80 to 130.degree.C using, as a cataLyst, a rhodium compLex which contains, as Ligands, sparingLy voLatiLe compounds of the generaL formuLa I 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 ant the recycLe gas in a separator, and the recycLe gas and the Liquid phase from the devoLatiLization coLumn are recycLed to the reactor. |
