A metallic reaction tube with a catalytic coating and a tube bundle reactor with coated reaction tubes are proposed, the coating containing a multimetal oxide mass which is applied directly to the reaction tubes, in particular to the inner wall / walls of the tube. The reaction tube or the tube bundle reactor are particularly suitable for use in the production process of (meth) acrolein and / or (meth) acrylic acid by catalytic gas phase oxidation. |
