Abstract: Oxidn. catalysts contg. Sn, Fe, Mn, Ti, Cu and/or Ni in addition to Os, Mo and/or W as well as V are used for the gas phase oxidn. of butenes to AcOH with O2-contg. gases in the presence of steam at 180-400 degrees C (esp. 250-350 degrees C). AcOH is obtd. in high yields, e.g. 87 mol %, and is suitable for prodn. of ester solvents. Butene conversion is high, e.g. 95 mol.%. Maleic acid is also obtd. in industrially utilisable yields, e.g. 4 mol.%. Spec. catalysts contain Mo, W, V and Sn and/or Fe and/or Mn and/or Cu and/or Ni in 6:0.2-6:0.2-12:0. 05-4 (esp. 6:0.5-3:0.5-6:0.1-2) atomic ratio.
