    摘要： The invention relates to a tube bundle reactor with a flat feed hood. Alternatively, the release hood may also have a flat design. The flat design reduces the heat of reaction which arises in the hood in the case of reaction types which take place not only in the tube bundle (uncatalyzed reactions and reactions with homogeneously distributed catalyst). This greatly suppresses undesired reactions which already take place in the hood owing to accumulated heat, which achieves a higher selectivity in the case of thermally sensitive reactions. In addition, the thermal distribution within the hoods can be controlled precisely.The tube bundle reactor comprises a tube bundle which has a feed end which is connected to a feed hood of the tube bundle reactor, wherein the feed hood is configured in a flat design with a cross-sectional area at the feed end and an internal volume, and the ratio of internal volume to cross-sectional area is less than 0.35 m. The invention is further implemented by means of a process for operating a tube bundle reactor, comprising: introducing a reactant mixture into a tube bundle and converting at least a proportion of the reactant mixture within the tube bundle to a product. The introducing comprises: feeding the reactant mixture into an interior of a feed hood of the tube bundle reactor and passing the reactant mixture on into a feed end of the tube bundle in the form of a fluid stream. The fluid stream has a cross-sectional area on entry into the feed end, and the interior of the feed hood through which the fluid stream flows has an internal volume; where the ratio of internal volume to cross-sectional area is less than 0.35 m.
