Abstract: The heterogeneous catalytic continuous gas phase partial oxidation of an organic compound is conducted using compressed molecular oxygen, which also acts as an inert diluent gas. During compression, solid particles are mechanically removed from the molecular oxygen source.

Abstract: A process for preparing hydroformylation products of propylene and for preparing acrylic acid and/or acrolein comprises a) feeding a propylene-containing feed in which from 2 to 40% by weight of propane is present and also carbon monoxide and hydrogen into a reaction zone and reacting this mixture in the presence of a hydroformylation catalyst to form hydroformylation products of propane, b) separating a stream consisting essentially of unreacted propylene and propane from the output from the reaction zone, and c) subjecting the stream consisting essentially of propylene and propane to a catalytic gas-phase oxidation in the presence of molecular oxygen to form acrylic acid and/or acrolein.

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: In a process for preparing acrylic acid, an acrylic acid-containing product gas mixture obtained by catalytic gas phase partial oxidation of a C 3 precursor of acrylic acid, after direct cooling with a quench liquid, is fractionally condensed in a separating column provided with internals, rising into itself with sidestream takeoff of crude acrylic acid, and the acrylic acid oligomers which form are dissociated and the resulting dissociation gas is subjected to a countercurrent rectification before it is recycled.

Abstract: In a process for the catalytic gas-phase oxidation of acrolein to acrylic acid, the reaction gas starting mixture is passed, with an acrolein loading of >=150 l (s.t.p.)/l.h, over a fixed-bed catalyst which is housed in two spatially successive reaction zones A, B, the reaction zone B being kept at a higher temperature than the reaction zone A.
