Separating acrylic acid comprises cooling product gas mixture of partial gas phase oxidation of three carbon precursor compound in cooler and providing cooled product gas mixture with (non)evaporated cooling liquid into absorption column

Partial gas phase oxidation of acrolein to acrylic acid or methacrolein to methacrylic acid, useful e.g. as monomer to prepare polymers, comprises using a tube bundle reactor in reaction tube of a vertically arranged reaction tubes

Separating acrylic acid from a product gas mixture of heterogeneously catalyzed partial gas phase oxidation of a precursor compound to acrylic acid comprises cooling product gas mixture and adding cooled mixture into absorption column
