Abstract: front page image
(EN)The present invention relates to the manufacture of dialkylaminoalkyl (meth)acrylate, in particular N,N-dimethylaminoethyl acrylate, by transesterification reaction of an alkyl (meth)acrylate with an amino alcohol, and the subject matter thereof is more particularly a process for recovering the heavy by-products generated during this manufacture, enabling the recycling of noble products on the dialkylaminoalkyl (meth)acrylate purification unit.
(FR)La présente invention concerne la fabrication de (méth)acrylate de dialkylaminoalkyle, en particulier l'acrylate de N,N-diméthyl aminoéthyle, par réaction de transestérification d'un (méth)acrylate d'alkyle avec un aminoalcool, et a plus particulièrement pour objet un procédé de valorisation des sous- produits lourds générés au cours de cette fabrication, permettant le recyclage de produits nobles sur l'unité de purification du (méth)acrylate de dialkylaminoalkyle.
