Abstract
La présente invention a pour objet un procédé de production d'acide méthacrylique ou acrylique par oxydation de méthacroléine ou d'acroléine par l'oxygène moléculaire en présence de vapeur d'eau. Elle est caractérisée en ce que l'on met le mélange réactionnel au contact d'un catalyseur contenant, à titre de constituants majeurs, du palladium, du phosphore, de l'antimoine, de l'oxygène, et au moins un métal X appartenant à la liste formée par le groupe des métaux suivants : potassium, sodium, rubidium, lithium, cérium, béryllium, magnésium, calcium, vanadium, strontium, zinc, thorium et rhénium. Elle se rapporte à ces catalyseurs et à leur emploi.
