Abstract
A reactor () of high cylindrical construction for continuously carrying out gas-liquid, liquid-liquid or gas-liquid-solid reactions, provided with a downward-directed jet nozzle () via which the starting materials and the reaction mixture are fed in and which is located in the upper region of the reactor, and provided with an offtake (), preferably in the lower region of the reactor, via which the reaction mixture is conveyed via an external circuit back to the jet nozzle () by means of a pump (P), wherein a guide tube () which extends essentially over the total length of the reactor () with the exception of the reactor ends and has a cross-sectional area in the range from one tenth to one half of the cross-sectional area of the reactor () is located concentrically in the reactor (), and the jet nozzle () is located above the upper end of the guide tube (), preferably at a distance of from one eighth of the guide tube diameter to one guide tube diameter, or projects into the guide tube () to a depth up to a plurality of guide tube diameters is proposed. A heat exchanger, in particular a heat exchanger having heat exchange tubes (), preferably running parallel to the guide tube, welded in between plates (), is integrated into the annular space.
