Title (EN) NOVEL HETEROPOLYACID CATALYST AND METHOD FOR PRODUCING THE SAME
(FR) NOUVEAU CATALYSEUR HETEROPOLYACIDE ET SON PROCEDE DE PRODUCTION
Abstract: front page image
(EN)Provided is a novel heteropolyacid catalyst useful for partial oxidation of methacrolein (MACR) to methacrylic acid (MAA), as represented by the following formula 1: PMoaAbBcCdDeEfOg (1) wherein A, B, C, D, E, a, b, c, d, e, f, and g are as defined in the specification. Provided is also a method for producing the heteropolyacid catalyst. The heteropolyacid catalyst produced by the method exhibits excellent catalyst activity in terms of conversion rate, selectivity, and yield.
(FR)L'invention concerne un nouveau catalyseur hétéropolyacide utile pour une oxydation partielle de méthacroléine (MACR) en acide méthacrylique (MAA), comme représenté par la formule 1: PMoaAbBcCdDeEfOg (1), A, B, C, D, E, a, b, c, d, e, f et g ayant la définition donnée dans la description. L'invention concerne également un procédé de production du catalyseur hétéropolyacide. Le catalyseur hétéropolyacide produit par ce procédé a une excellente activité de catalyseur en termes de taux de conversion, de sélectivité et de rendement.
