Abstract

Methacrolein and methacrylic acid are separated from the gaseous reaction mixture obtained by catalytic oxidation of methacrolein or a methacrolein precursor by introducing the gaseous reaction mixture into a condenser wherein the reaction mixture is brought into direct countercurrent contact with condensed liquor previously obtained in the condenser to condense methacrylic acid and water vapour in the reaction mixture, introducing the gaseous residue into the bottom of a methacrolein-absorption tower wherein methacrolein in the gas is absorbed into an aqueous solution of methacrylic acid supplied to the top of the absorption tower, and sending the resulting methacrolein-containing, aqueous methacrylic acid solution obtained from the bottom of the tower to the top of a methacrolein-stripping tower while introducing the condensed liquor obtained by condensation of said gaseous reaction mixture into the middle part or top of the stripping tower wherein an inert gas is supplied to the bottom of the tower whereby methacrolein withdrawn from the top of the stripping tower and the aqueous methacrylic acid solution is withdrawn from the bottom.
