description The invention relates to the use of a column with a separating wall as a purification/finishing column in a (meth)acrylic acid recovery method based on the use of two distillation columns in the absence of external organic solvent. The method according to the invention improves the energy balance for the method while improving the technical quality of the (meth)acrylic acid recovered. The method according to the invention further produces polymer-grade (or glacial) (meth)acrylic acid compatible with the production of high-molecular weight acrylic acid polymers.
