Abstract

PROCEDE DE SYNTHESE D’OLIGOMERES D’ACIDE ACRYLIQUE L’invention a donc pour objet un procédé de synthèse d’un oligomère d’acide acrylique représenté par la formule (I) : dans laquelle n est un entier allant de 1 à 30, comprenant le chauffage d’acide acrylique à une température allant de 50°C à 200°C en présence d’un catalyseur et d’au moins un inhibiteur de polymérisation dans une zone de réaction, caractérisé en ce qu’un flux continu d’un gaz ou d’un mélange de gaz inerte est passé dans la zone de réaction entrainant l’élimination de l’essentiel de l’eau présente dans la zone de réaction sous forme d’évents gazeux. Le procédé selon l’invention permet de limiter la formation de l’acide 3-hydroxypropionique susceptible de constituer une impureté dans le produit final. 1/1
