Title (EN) PROCESS FOR PRODUCING (METH)ACRYLIC ESTERS
(FR) PROCEDE DE FABRICATION D'ESTERS (METH)ACRYLIQUES
Abstract:
(EN) The subject of the invention is a process for continuously producing a (meth)acrylic ester by transesterification reaction between a light C1-C4 alkyl (meth)acrylate and a heavy alcohol in the presence of a catalyst, characterized in that the streams supplying the reactor are introduced by means of a static mixer placed on a recirculation loop of the reactor. The use of a static mixer makes it possible to improve the selectivity of the reaction and consequently the overall productivity of the process for synthesizing (meth)acrylic esters.
(FR) L'invention a pour objet un procédé de fabrication en continu d'un ester (méth)acrylique par réaction de transestérification entre un (méth)acrylate d'alkyle léger en C1-C4, avec un alcool lourd en présence d'un catalyseur, caractérisé en ce que les flux alimentant le réacteur sont introduits par l'intermédiaire d'un mélangeur statique placé sur une boucle de recirculation du réacteur. L'utilisation d'un mélangeur statique permet d'améliorer la sélectivité de la réaction et en conséquence la productivité globale du procédé de synthèse d'esters (méth)acryliques.
