Title (EN) METHOD OF MAKING ACRYLIC ACID FROM LACTIC ACID OR LACTIDE USING MOLTEN SALT CATALYSTS
(FR) PROCÉDÉ DE FABRICATION D'ACIDE ACRYLIQUE À PARTIR D'ACIDE LACTIQUE OU DE LACTIDE À L'AIDE DE CATALYSEURS À BASE DE SEL FONDU
Abstract:
(EN) A method of making acrylic acid in liquid phase by contacting a feed stream containing lactic acid, lactide, or mixtures thereof with a molten salt catalyst comprising a protic ionic liquid (PIL), which contains a bromide anion (Br-), is provided.
(FR) L'invention concerne un procédé de fabrication d'acide acrylique en phase liquide par la mise en contact d'un flux d'alimentation contenant de l'acide lactique, du lactide ou des mélanges de ceux-ci avec un catalyseur à base de sel fondu comprenant un liquide ionique protique (PIL), qui contient un anion bromure (Br-).
