Title
(EN) AMINOALKYL (METH)ACRYLATE STABILISATION
(FR) STABILISATION DE (METH)ACRYLATES D'AMINOALKYLE
Abstract
(EN)
The invention relates to the use of a stabilising compound comprising at least one N-oxyl compound and at least one polymerisation inhibitor other than an N-oxyl compound, for inhibiting transesterification catalyst degradation in a process for the synthesis of aminoalkyl (meth)acrylates. Preferably, the transesterification catalyst is a titanium organometallic compound and the stabilising composition comprises at least one N-oxyl derivative and at least one polymerisation inhibitor chosen from phenolic compounds and phenothiazine compounds in a weight ratio of between 1 and 10, preferably between 4 and 10, limits inclusive.

L'invention porte sur l'utilisation d'une composition stabilisante comprenant au moins un composé N-oxyl et au moins un inhibiteur de polymérisation autre qu'un composé N- oxyl pour inhiber la dégradation du catalyseur de transestérification dans un procédé de synthèse de (méth)acrylates d'aminoalkyle. De préférence, le catalyseur de transestérification est un composé organométallique de titane et la composition stabilisante comprend au moins un dérivé N- oxyl et au moins un inhibiteur de polymérisation choisi parmi les composés phénoliques et les composés phénothiazine dans un rapport massique compris entre 1 et 10, de préférence entre 4 et 10 bornes comprises.
