Title
(EN) METHOD FOR PREPARING ACRYLIC ACID FROM β-PROPIOLACTONE
(FR) PROCEDE DE PREPARATION D'ACIDE ACRYLIQUE A PARTIR DE β-PROPIOLACTONE
Abstract
(EN) The present invention relates to a method for preparing acrylic acid from β-propriolactane and to the uses thereof. The process of the invention is based on a specific reactivity of β-propriolactane whereby acrylic acid is formed under operating conditions that are mild, especially in terms of temperature.
(FR) La présente invention concerne un procédé de préparation d'acide acrylique à partir de β-propiolactone et ses utilisations. Le procédé de l'invention repose sur une réactivité spécifique de la β-propiolactone qui, dans des conditions opératoires douces notamment en termes de température, conduit sélectivement à la formation de l'acide acrylique.
