    Abstract: The invention relates to a multi-tube fixed-bed reactor and to the use of a reactor of this type for carrying out catalytic gas phase reactions, especially for carrying out exothermic or endothermic catalytic gas phase reactions such as producing phthalic anhydride (PSA), acrylic acid (AA), methacrylic acid (MAA), acrolein, maleic anhydride (MSA), glyoxal, phosgene, hydrogen cyanide or vinyl formamide (VFA). According to the invention, in the case of larger reactors where a considerable reaction heat is produced or required and must be dissipated as a result of the numerous reaction tubes (17), the ratio of tube distribution t to tube outer diameter d?a? is made dependant on the reactor diameter or the tube bundle diameter d?RBa?. If the outer diameter of the reaction tube bundle (18) is more than 4 metres, a ratio of tube distribution t to tube outer diameter d?a? of at least 1.3 is preferred.

    Abstract: A multitube fixed bed reactor and the use of such a reactor for carrying out catalytic gas-phase reactions, in particular for carrying out exothermic and endothermic catalytic gas-phase reactions such as the preparation of phthalic anhydride (PA), acrylic acid, methacrylic acid (MAA), acrolein, maleic anhydride (MA), glyoxal, phosgene, hydrocyanic acid or vinyl formamide (VFA). In a relatively large multitube reactor in which a large amount of heat of reaction is generated owing to the numerous catalyst tubes ( 17 ) and has to be removed, it is proposed that the ratio of tube spacing t to external tube diameter d a be made dependent on the reactor diameter or on the external tube bundle diameter d RBa . At an external diameter of the catalyst tube bundle ( 18 ) of more than 4 meters, a ratio of tube spacing d to external tube diameter d a of at least 1.3 is preferred.

    Abstract: The invention relates to a method for the catalytic vapour-phase partial oxidation of aromatic hydrocarbons to form carboxylic acids or carboxylic acid anhydrides at an increased temperature. According to said method, a vapour stream charged with the educt is guided through a multi-tube flow reactor, said reactor being maintained at the correct temperature by means of one or more separate thermostatic baths, which have a counter-current circulation in relation to the educt vapour stream. The difference between the temperature of the thermostatic bath in the vicinity of the reactor outlet and the temperature of the product vapour stream that leaves the reactor is used to control the selectivity of the vapour-phase oxidation.
