Abstract: THE INVENTION PROPOSES A REACTOR (1) HAVING A CONTACT TUBE BUNDLE (2) THROUGH WHOSE SPACE SURROUNDING THE CONTACT TUBES A HEAT-EXCHANGE MEDIUM CIRCUIT IS PASSED, WITH RING LINES (3, 4) AT BOTH ENDS OF THE REACTOR WITH JACKET APERTURES (5, 6) FOR THE SUPPLY AND DISCHARGE OF A HEAT-EXCHANGE MEDIUM BY MEANS OF A PUMP VIA AN EXTERNAL HEAT EXCHANGER, WHERE THE HEAT-EXCHANGE MEDIUM IS FED TO THE LOWER RING LINE (4) AND IS DISCHARGED TO THE HEAT EXCHANGER VIA THE UPPER RING LINE (3), AND WITH BAFFLE PLATES (7) WHICH LEAVE A PASSAGE CROSS SECTION ALTERNATELY IN THE REACTOR CENTER AND AT THE REACTOR EDGE. THE UPPER (3) AND LOWER (4) RING LINES ARE EACH DIVIDED INTO AN INNER (11, 13) AND AN OUTER (12, 14) RING LINE BY A CYLINDRICAL PARTITION WALL (8, 9), AND THE HEAT-EXCHANGE MEDIUM IS FED TO THE OUTER LOWER RING LINE (14), VIA A REGION OUTSIDE THE REACTOR TO THE INNER UPPER RING LINE (11), VIA THE JACKET APERTURES (5) OF THE LATTER TO THE REGION SURROUNDING THE CONTACT TUBES (2), VIA THE JACKET APERTURES (6) TO THE INNER LOWER RING LINE (13) AND SUBSEQUENTLY VIA A REGION OUTSIDE THE REACTOR TO THE OUTER UPPER RING LINE (12).

Abstract: Method for preparing (meth)acrolein and/or (meth)acrylic acid by partial gas-phase oxidation of 3-4C precursors in presence of a heterogeneous, particulate catalyst (A). Method for preparing (meth)acrolein and/or (meth)acrylic acid by partial gas-phase oxidation of 3-4C precursors in presence of a heterogeneous, particulate catalyst (A). Oxidation is done in a reactor having 2 or more vertical thermal plates (1), arranged in parallel and with gaps (2) between them, where (2) contain the catalyst and the gaseous reaction mixture is supplied to (2). The new feature is that the method is monitored, controlled and/or regulated through one or more temperature measurements, taken in one or more (2), at one or more measuring sites, distributed over the height of each (2). An independent claim is also included for a method of incorporating temperature-measuring devices into a reactor, on the same side of the reactor as the feed line for supplying gaseous reaction mixture.
