"Method For Purifying The Azeotropic Fraction Generated During The Synthesis Of N, N Dimethylaminoethyl Acrylate"
Abstract: The invention relates to a method for producing N,N-dimethylaminoethyl acrylate by the transesterification reaction of an alykl acrylate by NIN-dimethylaminoethanol, and more particularly relates to a method for purifying the azeotropic fraction generated during said reaction, thereby enabling the recycling thereof on the alkyl acrylate production unit. The aim of the method of the invention is in particular to remove the acetaidehyde and the dialkoxyethane contained in the azeotropic fraction, either by the direct distillation of the azeotropic fraction or by the distillation of the aqueous phase resulting from the water scrubbing of the azeotropic fraction.
