A process for the continuous production of (meth) acrylic acid fromnthe reaction gases of a catalytic gas phase oxidation by (I) absorption inna high-boiling solvent, (II) separation of the (meth) acrylic acid from thenMix with the solvent and, if necessary, further purify the separatedn(Meth) acrylic acid, (III) cleaning the solvent and (IV)nReturn of the cleaned solvent to the absorption stage (I)nproposed, the temperature in each process stage 155 ° C, in particularn140 ° C, preferably does not exceed 120 °. |
