Abstract: Process comprises a catalytic oxidation of indanes of formula (I), using oxygen in the gaseous phase (R1, R2, R3 same or different, are each alkyl, or R1 and/or R3 may be H). Specif. 1-methyl-3-phenyl-indane is catalytically oxidised by air at 160-500 degrees C, pref. using a supported iron-vanadium catalyst. Anthraquinone is a starting material for dyestuffs and pesticides.

Abstract: Catalysts for the preparation of carboxylates from an aldehyde and an alkanol in the presence of oxygen, which contain palladium and lead as active components, these being present on a carrier containing zinc oxide, and the palladium being applied as a palladium salt in a solution containing hydrochloric acid and then being liberated by reduction, and whose carrier consists solely of zinc oxide, are particularly active and selective.

Abstract: Acrylic acid practically devoid of water, acrolein, formaldehyde and acetic acid is obtained at particularly low cost by countercurrent scrubbing and quenching of the reaction gas formed in the catalytic oxidation of propylene and/or acrolein with a high-boiling, extremely hydrophobic solvent followed by processing of the extract.
