process for preparing acrylic acid |
| abstract |
PROCESS TO PREPARE ACRYLIC ACID. A process for preparing acrylic acid, in which a gaseous product mixture comprising acrylic acid obtained by partial oxidation of the catalytic gaseous phase of a C3 precursor to acrylic acid is fractionally condensed in a condensation column provided with internal elements ascending by itself. with side drainage removal of crude acrylic acid and with drainage removal of the liquid phase of acidic water comprising acrylic acid and acrylic acid present in acidic water is collected in a solvent for extraction and then removed from the solvent for extraction and recycled in the condensation column, or collected in aqueous metal hydroxide or sent for further purification of the crude acrylic acid. |
