Abstract

The invention relates to a catalytic process for carrying out multiphase reactions in a tubular reactor, with the catalyst being present in the continuous phase and at least one starting material in a disperse phase and the loading factor B of the tubular reactor being equal to or greater than 0.8. The process is especially suitable in particular for the hydroformylation of olefins. The aldehydes thus prepared can ideally be used for the preparation of alcohols, carboxylic acids or in aldol condensations.
