Abstract: The invention relates to a vertical cylinder reactor (1) for carrying out gas-liquid, liquid-liquid or gas-liquid-solid chemical reactions. Said reactor comprises a nozzle (2) which is arranged in the upper portion of the reactor and which is directed downwards and by way of which the educts and the reaction mixture are supplied. The reactor further comprises a discharge (3), preferably in the lower portion of the reactor, through which the reaction mixture can be re-fed to the nozzle (2) via an exterior circuit by way of a pump (P). A concentric guide tube is arranged in the reactor which substantially extends across the entire length of the reactor (1) except the reactor ends. Said guide tube has a cross-sectional area in the range of a tenth to half of the cross-sectional area of the reactor (1). The nozzle is arranged above the upper end of the guide tube (4), preferably in a distance of an eighth to a full cross-sectional area of the guide tube or it dips into the guide tube (4) in a depth of up to several cross-sectional areas of the guide tube. A heat exchanger is integrated into the annulus, especially a heat exchanger with heat exchanger tubes (6) welded between bottoms (6). Said tubes are preferably arranged parallel to the guide tube.
