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: A method for using a clamp for detachable connection of a column tray to a support ring in a column including using a clamp which includes a bolt lower clamp part connected to the bolt. The lower clamp part has at least one orifice through which a liquid present in the column can flow away.

Abstract: In a process for the catalytic gas-phase oxidation of propene to acrolein, the reaction gas starting mixture is passed with a propene loading of >=160 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.

Abstract: Organic compound(s) is prepared by heterogeneously catalyzed partial gas-phase oxidizing of organic precursor compound(s) in a reactor loaded with catalyst, and bringing portion of components of the reaction gas starting mixture from low initial pressure to higher final pressure using a compressor. The compressor used is a radial compressor.

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.
