SOLUTION: (Meth)acrylic acid is reacted with a 1-5C alkanol in (1:0.75) to (1:2) molar ratio and an organic phase from a rectifier III above a reaction zone is returned to the rectifier and water phase is removed from the system and water is added to a reaction mixture discharged from the reaction zone and the reaction mixture is fed to the rectifier I and separated into a product II containing residual (meth)acrylic acid and a product I containing residual alkanol and water in the rectifier I and the product 11 is returned to the reaction zone and the product from the rectifier I is separated into a (meth)acrylic acid alkyl ester-containing organic phase and water phase and the organic phase is fed to the rectifier II and the residual alkanol is separated from the (meth)acrylic acid alkyl ester and returned to the reaction zone.
