Title (EN) IMPROVED METHOD FOR TRANSESTERIFICATION
(FR) PROCEDE AMELIORE DE TRANSESTERIFICATION
Abstract:
(EN) An improved method for transesterification of acrylate and alkyl acrylate esters. The improved method comprises the use of at least one aromatic amine compound having no acidic or ionic groups. The improved inhibitor system enhances the reaction rate of the transesterification reaction while simultaneously maintaining adequate polymerization suppression. The reaction is catalyzed by a basic catalyst, and can be driven by the removal of alcohol as an alcohol/saturated hydrocarbon azeotrope.
(FR) L'invention concerne un procédé amélioré de transestérification d'esters acrylate et alkyle acrylate. Ce procédé consiste à utiliser au moins un composé d'amine aromatique ne possédant pas de groupes acides ou ioniques. Le système inhibiteur amélioré augmente la vitesse de la réaction de transestérification tout en maintenant simultanément la suppression adéquate de la polymérisation. La réaction est catalysée par un catalyseur basique et peut être effectuée par élimination de l'alcool sous forme d'un mélange azéotropique alcool/hydrocarbure saturé.
