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.

Abstract: 1298504 Cyanoacetaldehyde; isoxazolines BADISCHE ANILIN. & SODA-FABRIK AG 21 April 1970 [22 April 1969] 18917/70 Heading C2C Cyanoacetaldehyde is obtained by splitting in the presence of alkali-metal or alkaline-earthmetal oxides or hydroxides, either (a) isoxazolines of the formula wherein R is an aromatic radical; or (b) isoxazolines obtained by reacting malonaldehyde dioxime with nitrous acid. Phenyl azide may be produced as a by-product of the above-process, when R is a phenyl group. Isoxazolines of the above formula may be obtained by reacting malonaldehyde dioxime with appropriate diazonium compounds.
