Hydroformylation of olefins is carried out in a vertical tubular reactor with a circulation loop, a nozzle at the top, an internal guide tube and a baffle plate below the tube, so that a stream of liquid with gas bubbles is forced down the tube, deflected into the upward liquid stream in the space between tube and reactor wall and sucked back into the tube. A process for the production of aldehydes and/or alcohols or amines by the liquid-phase reaction of olefins with carbon monoxide and hydrogen (this gas mixture being partly in the form of bubbles and partly dissolved in the reaction liquid) at elevated temperature and 1-100 bar in the presence or absence of a prim. or sec. amine and in presence of homogeneously dissolved cobalt-, rhodium-, palladium- or ruthenium-carbonyl complexes with phosphorus-, arsenic-, antimony- or nitrogen-containing ligands. The reaction is performed in a vertical tubular reactor comprising a reactor body and at least one circulating loop, by means of which part of the reaction liquid is continuously fed into a nozzle at the top of the reactor and thence into an internal guide tube with parallel walls, open at the top and bottom and with a baffle plate mounted under the lower end. This produces a downward stream of liquid with dispersed gas bubbles, which is deflected by the baffle plate into a stream flowing upwards in the space between the tube and the reactor wall and then sucked into the top of the guide tube by the jet from the nozzle. |
