摘要： The invention relates to a method for the production of acrylic acid. A product gas mixture, comprising acrylic acid, obtained by catalytic, partial, gas-phase oxidation of an acrylic acid C3 precursor, is fractionally condensed in a rising, packed separating column after direct cooling with a quenching fluid to give crude acrylic acid as a side stream and the acrylic acid oligomers which are formed are cleaved and the resulting cleaved gasses are subjected to a counter-current rectification before recycling.

摘要： Disclosed is a method for producing propylene hydroformylation products and acrylic acids and/or acrolein, whereby a) an inflow containing propylene and 2 to 40 wt. % propane, as well as carbon monoxide and hydrogen, are fed into a reaction zone and converted into propene hydroformylation products in the presence of a hydroformylation catalyst, b) a flow consisting essentially of unreacted propylene and propane is separated from the discharge from the reaction zone, and c) said flow consisting essentially of propylene and propane is subjected to catalytic gas phase oxidation, in the presence of molecular oxygen, to obtain acrylic acid and/or acrolein.

摘要： The invention relates to a method for the catalytic gas phase oxidation of propene into acrylic acid in which the initial mixture of reaction gas, with an increased propene charge, is oxidized on a first fixed-bed catalyst during a first reaction step, said fixed-bed catalyst being accommodated in two reaction zones A, B arranged in a spatially successive manner, whereby the temperature of reaction zone B is kept at a higher temperature than that of reaction zone A. In addition, the mixture of product gas which contains acrolein and which is of the first reaction step is, under an increase acrolein charge, subsequently oxidized on a second fixed-bed catalyst during a second reaction step. Said second fixed-bed catalyst is accommodated in two successively arranged reaction zones C, D, whereby the temperature of reaction zone D is kept at a higher temperature than that of reaction zone C.
