Compositions of matter and catalyst compositions effective for gas-phase conversion of propane to acrylic acid (via oxidation) or to acrylonitrile (via ammoxidation) and isobutane to methacrylic acid (via oxidation) and isobutane to methacrylonitrile (via ammoxidation) are disclosed. Preferred catalyst compositions comprise molybdenum, vanadium, niobium, antimony and germanium and molybdenum, vanadium, tantalum, antimony, and germanium. Methods of preparing such compositions and related compositions, including hydrothermal synthesis methods are also disclosed. The preferred catalysts convert propane to acrylic acid and/or to acrylonitrile and isobutane to methacrylic acid/methacrylonitrile with a yield of at least about 50 %.
La présente invention a trait à des compositions de matière et des compositions de catalyseurs efficaces pour la conversion en phase gazeuse de propane en acide acrylique (par oxydation) ou en acrylonitrile (par ammoxydation) et d'isobutane en acide méthacrylique (par oxydation) et d'isobutane en méthacrylonitrile (par ammoxydation). Des compositions de catalyseurs préférées comprennent le molybdène, le vanadium, le niobium, l'antimoine et le germanium et le molybdène, le vanadium, le tantale, l'antimoine et le germanium. L'invention a également trait à des procédés de préparation de telles compositions et de compositions associées, y compris des procédés de synthèse hydrothermique. Les catalyseurs préférés convertissent le propane en acide acrylique et/ou en acrylonitrile et l'isobutane en acide méthacrylique/méthacrylonitrile avec un rendement d'au moins 50 %.
