    摘要： A process for preparing C1-C4-oxygenates from a reactant stream A which comprises essentially a C1-C4-alkane or a mixture of C1-C4-alkanes, by a) branching off a substream B of the reactant stream A and allowing it to react in a reactor with oxygen or an oxygenous gas stream C, which converts a portion of the C1-C4-alkane or a portion of the mixture which comprises C1-C4-alkanes to C1-C4-oxygenates, b) removing at least 90 mol % of the C1-C4-oxygenates formed from the product stream D resulting from step a) to form a remaining low boiler stream E, which comprises combining the low boiler stream E with the reactant stream A without further workup and without combination with the substream B down-stream of the branching site of the substream B.

    摘要： The present invention relates to a catalyst for the oxidation of o-xylene and/or naphthalene to phthalic anhydride, which has a plurality of catalyst zones which are arranged in series in the reaction tube and have been produced using an antimony trioxide which comprises a significant proportion of valentinite. The present invention further relates to a process for gas-phase oxidation, in which a gas stream comprising at least one hydrocarbon and molecular oxygen is passed through a catalyst produced using an antimony trioxide which comprises a significant proportion of valentinite.
