Abstract

In a process for preparing aldehydes and/or alcohols having from 6 to 30 carbon atoms by hydroformylation of olefins by means of synthesis gas in the presence of a catalyst at from 120° C. to 210° C. and pressures of from 100 to 400 bar, a reaction mixture comprising olefins, synthesis gas and catalyst or catalyst precursor is, according to the present invention, introduced at high velocity into a high-pressure reactor via a nozzle having an adjustable flow cross section.
