Abstract: The invention relates to a method for producing alkyl(meth)acrylate by continuous reaction of an aqueous solution containing (meth)acrylic acid obtained directly from gas-phase oxidation by reacting with a straight-chain or branched alkanol with 1 to 6 C atoms or a mixture of two or more thereof in the presence of an esterification catalyst. The inventive method is characterized in that alkanol is introduced into aqueous solution containing (meth)acrylic acid in the form of a gas.
