Abstract: The invention relates to a method for producing acrylic acid by means of two-stage heterogeneously catalyzed partial gas phase oxidation of propylene. According to said method, previously dehydrogenated propane is used as a propylene source while the first partial oxidation stage is operated so as to limit propylene reaction. Furthermore, unreacted propane and propylene contained in the product gas mixture of the second partial oxidation stage are largely redirected into the propane dehydrogenation process taking place upstream.

Abstract: A process for preparing acrylic acid, in which an acrylic acid-comprising product gas mixture obtained by catalytic gas phase partial oxidation of a C3 precursor of acrylic acid is fractionally condensed in a condensation column provided with internals ascending into itself with side draw removal of crude acrylic acid and with liquid phase draw removal of acrylic acid-comprising acid water, and acrylic acid present in acid water is taken up into an extractant and then removed from the extractant and recycled into the condensation column, or taken up in aqueous metal hydroxide, or sent to further purification of the crude acrylic acid.

Abstract: A process for storing a monomer phase which is liquid under the conditions of storage and comprises methacrylic monomers to an extent of ≧95% by weight and has been obtained by condensation out of a gaseous phase or by melting a crystalline phase, in a storage vessel, in which polymer of the monomer present in dissolved form in the liquid monomer phase is removed therefrom on the route from its generation into the storage vessel, and also a process for withdrawing liquid monomer phase from the storage vessel in which polymer of the monomer present in dissolved form in the monomer phase is likewise removed.

Abstract: Heterogeneously catalyzed gas phase partial oxidation of organic compound with oxygen over fixed catalyst bed involves: recovering quality of the fixed catalyst bed by not replacing entire fixed catalyst bed but only its portion by a replacement fixed catalyst bed part; when increasing operating time is accompanied by increasing reduction in quality of the fixed catalyst bed, such that volume-specific activity of the replacement fixed catalyst bed part is lower than volume-specific activity of replaced fixed catalyst bed part in its freshly installed state. Method for heterogeneously catalyzed gas phase partial oxidation of at least one organic starting compound with molecular oxygen over a fixed catalyst bed freshly installed into a reaction chamber, involving conducting a reaction gas mixture comprising the at least one organic starting compound and the molecular oxygen through the fixed catalyst bed, for partial oxidation; and removing the heat of reaction by indirect heat exchange with a fluid heat carrier conducted outside the reaction chamber, involves: recovering the quality of the fixed catalyst bed by not replacing the entire fixed catalyst bed but only its portion by a replacement fixed catalyst bed part; when increasing operating time is accompanied by an increasing reduction in the quality of the fixed catalyst bed, such that the volume-specific activity of the replacement fixed catalyst bed part is lower than the volume-specific activity of the replaced fixed catalyst bed part in its freshly installed state.

Abstract: A 3C or more of precursor is subjected to heterogeneously catalyzed gas phase partial oxidation with molecular oxygen in solid-state catalyst to obtain product gas mixture. The product gas mixture is reduced by direct cooling, passed into a condensation column, and crude acrylic acid is conducted, and acid water is disposed. A residual gas mixture is recycled, and crude acrylic acid is subjected to thermal separation process. The acrylic acid is taken in organic solvent to form organic extract, and thermal separation processed to form acrylic acid. A 3C or more of precursor is subjected to heterogeneously catalyzed gas phase partial oxidation with molecular oxygen in solid-state catalyst at elevated temperature to obtain product gas mixture comprising acrylic acid, steam and secondary components. The product gas mixture is reduced by direct/indirect cooling, passed into a condensation column equipped with separating internals, allowed to ascend into the condensation column, and fractionally condensed. The crude acrylic acid comprising water and secondary components, is conducted as the target product from the condensation column through a side draw (A1) disposed above the feed point of the product gas mixture into the condensation column, and acid water comprising acrylic acid and secondary components is disposed above the side draw (A1) through a liquid phase draw (A2). A residual gas mixture comprising secondary components having lower boiling points than water at the top of the condensation column and a bottoms liquid comprising acrylic acid and conversion products, and secondary components having higher boiling points than acrylic acid from the bottom space of the condensation column, is recycled after cooling with reflux liquid, into the condensation column, and the crude acrylic acid is subjected to thermal separation process and purified. The acrylic acid in a portion of acid water not recycled into the condensation column is taken up from the acid water into an organic solvent by extraction with the organic solvent to form an organic extract comprising acrylic acid. The acrylic acid is removed from the organic extract using thermal separation process, and the acrylic acid removed from the extract is recycled into the condensation column into the aqueous solution of a metal hydroxide. Thus, acrylic acid is manufactured.
