Title (EN) CATALYSTS FOR THE PRODUCTION OF ACRYLIC ACID OR ITS DERIVATIVES
(FR) CATALYSEURS DE PRODUCTION D'ACIDE ACRYLIQUE OU DE SES DÉRIVÉS
Abstract: front page image
(EN)Catalysts for dehydrating hydroxypropionic acid, hydroxypropionic acid derivatives, or mixtures thereof to acrylic acid, acrylic acid derivatives, or mixtures thereof with high yield and selectivity, short residence time, and without significant conversion to undesired side products, such as, for example, acetaldehyde, propionic acid, and acetic acid, are provided. The catalysts are mixed protonated monophosphates. Methods of preparing the catalysts are also provided.
(FR)L'invention concerne des catalyseurs de déshydratation d'acide hydroxypropionique, de dérivés d'acide hydroxypropionique ou de leurs mélanges en acide acrylique, en dérivés d'acide acrylique ou en leurs mélanges, avec un rendement et une sélectivité élevés, un temps de séjour court, et sans conversion notable en sous-produits indésirables tels que, par exemple, l'acétaldéhyde, l'acide propionique ou l'acide acétique. Ces catalyseurs sont un mélange de monophosphates protonés. L'invention concerne également des procédés de préparation des ces catalyseurs.
