Abstract

Aldehydes are prepared in a hydroformylation apparatus by the multiphase hydroformylation reaction of one or more olefins with hydrogen and carbon monoxide, where the continuous phase contains a solvent mixture and the hydroformylation catalyst is present in the continuous phase, at least one olefin is present in the dispersed phase, and the loading factor of the tube reactor is greater than or equal to 0.8.
