Abstract: Production of anthraquinone by catalytic oxidation of indans with oxygen in the presence of a vanadium (V) compound with one or more than one compound of thallium and antimony. Anthraquinone which can be prepared by the process according to this invention is a valuable starting material for the production of dyes and pesticides.

Abstract: Benzoylbenzoic acid prepn. Oxidation of indanes of formula:- (R1, R2, R3 are each alkyl; R1 and/or R3 can be H), oxidised with HNO3 and/or Cr-VI compounds gives, simply and economically, better yields of high-purity o-benzoylbenzoic acid (valuable for syntheses, especially for anthraquinone) without formation of considerable quantities of o-acetylbenzophenone. Temperature for HNO3 oxidation is 50 - 250 degrees C. Less than 1.5 x stoichiometric requirement of Cr-VI compounds is preferred. In a preferred method, at least 10% stoichiometric requirement of alkaline bichromate is added simultaneously to the HNO3.

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.
