| titleOfInvention | Process for production of acrylic acid |
| abstract | The present invention provides an improved process for obtaining acrylic acid by subjecting propylene and / or acrolein to catalytic gas phase oxidation as a gas containing oxygen molecules. In this method, an aqueous acrylic acid solution is produced by contacting a mixed gas obtained by catalytic gas phase oxidation with an aqueous collector containing acrylic acid, acetic acid and a poorly water-soluble solvent; Azeotropic distillation is carried out in an aqueous acrylic acid solution in the presence of a solvent which is poorly water-soluble to remove by-products and to obtain high purity acrylic acid. |
