Abstract:
1. A reactor ( 1 ) of high cylindrical construction for continuously carrying out gas-liquid-solid reactions, provided with a downward-directed jet nozzle ( 2 ) 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 ( 3 ), preferably in the lower region of the reactor, via which the reaction mixture is conveyed via an external circuit back to the jet nozzle ( 2 ) by means of a pump (P), where a guide tube ( 4 ) which extends essentially over the total length of the reactor ( 1 ) 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 ( 1 ) is located concentrically in the reactor ( 1 ), and the jet nozzle ( 2 ) is located above the upper end of the guide tube ( 4 ), preferably at a distance of from one eighth of the guide tube diameter to one guide tube diameter, or projects into the guide tube ( 4 ) to a depth up to a plurality of guide tube diameters, and a heat exchanger provided with heat exchange tubes is integrated into the annular space, wherein the heat exchanger tubes run parallel to the guide tube ( 4 ).
