Beschreibung
Zusammenfassung:	The invention relates to a method for producing a (meth)acrylic ester with improved productivity, by transesterfication of a light alkyl (meth)acrylate with a heavy alcohol. The method of the invention includes the recycling of noble products recovered after the thermal treatment of heavy fractions generated during the synthesis, said thermal treatment being carried out in the presence of a dialkyl phthalate, the alkyl chain of which corresponds to that of the light alkyl (meth)acrylate. The invention applies to the production of N,N-dimethyaminoethyl acrylate from ethyl acrylate.
