| titleOfInvention | Continuous recovery of (meth)acrylic acid |
| abstract | A process for the continuous recovery of (meth) acrylic acid from the reaction gases of a catalytic gas-phase oxidation by (I) absorption in a high-boiling solvent, (II) isolation of the (meth)acrylic acid from the mixture with the solvent and, if required, further purification of the (meth)acrylic acid isolated, (III) purification of the solvent and (IV) recycling of the purified solvent to absorption stage (I) is proposed, the temperature in each process stage not exceeding 155° C., in particular 140° C., preferably 120° C. |
