Abstract
L'invention concerne un procédé de préparation simultanée d'acide méthacrylique et d'un méthacrylate ou d'acide acrylique et d'un acrylate. On fait réagir de la méthacroléine ou de l'acroléine avec un alcool aliphatique, de l'oxygène moléculaire en phase vapeur, en présence d'un catalyseur comprenant du palladium, du phosphore, de l'antimoine, un élément X et de l'oxygène, X representant un élément tel que le potassium, le sodium, le lithium, le rubidium, le cérium, le béryllium, le plomb, le magnésium, le calcium, le strontium, le zinc, le baryum, le thorium, le bismuth, le chrome, le fer, le nickel, le cobalt, le vanadium, le manganèse, l'étain, l'uranium et le rhénium. Le catalyseur est thermiquement stable et présente une durée de vie prolongée, assurant une sélectivité et un rendement élevés.
