Abstract: front page image
(DE)Die Erfindung betrifft ein Verfahren zur Herstellung von Acrolein aus Glycerin unter Verwendung eines sauren Festkörperkatalysators, der Wolframverbindungen und weitere Promotoren enthält. Ferner wird ein Verfahren insbesondere zur Herstellung von Methylmercaptopropionaldehyd aus Glycerin in Gegenwart des Katalysators beschrieben.
(EN)The invention relates to a method for producing acrolein from glycerine using a solid acid catalyst containing tungsten compounds and further promoters. Furthermore, a method, in particular, for producing methylmercaptopropionaldehyde from glycerine in the presence of the catalyst, is disclosed.
(FR)L'invention concerne un procédé de fabrication d'acroléine à partir de glycérine, au moyen d'un catalyseur solide acide contenant des composés de tungstène et d'autres promoteurs. L'invention concerne également un procédé notamment destiné à la fabrication de méthylmercaptopropionaldéhyde à partir de glycérine, en présence du catalyseur.
