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: Novel coated catalysts and a process for their preparation by atomizing a mixture of water and a vanadium-V compound, with or without other metal compounds, and applying this mixture to carrier particles which are themselves in motion, drying the coating and subjecting the catalyst particles, which are themselves in motion, to repeated brief treatment with a flame or plasma, followed by rapid cooling, defined temperatures and rates of coating being employed. The catalysts may be used with advantage for the preparation of anthraquinones by oxidation of indans.

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: The process involves (1) Adding a mixture of C4 hydrocarbons (I) of which >=50% are linear and olefinically unsatd. to air, heated to 100-200 degrees C. (2) Adding a volatile organic or mineral phosphorus cpd (II). (3) Passing the mixture through a tubular reactor at 420-600 degrees C lined with catalyst contg. 45-95% TiO2, 0.2-20% V2O5 and 3-53% P2Ok. (4) HEat exchange being carried out by a circulated salt bath at 350-440 degrees C supplied at one end of the reactor at constant flow through an annular tube and discharging from the other end of the reactor through a second annular tube. (5) Cooling the reacted mixture to 160-180 degrees C and washing it to extract maleic anhydride using cold aqs. maleic acid soln. which is obtained at concn. 30-50%. (6) Evaporating the soln. to >90% conc. in thin film evaporators. (7) Splitting maleic anhydride and water vapour in another evaporator. (8) Refining the crude product by continuous fractionation. (I) may contain 0-30% butadiene, 20-100% n-butenes, 0-50% isobutene and 10-50% butanes where the total of butadiene and n-butenes is >=50%. (II) is a trialkyl 1-4C phosphate. Content of (I) is 25-40g/m3 normal of the heated air. The process uses cheaper raw materials, than known maleic anhydride production precesses, and is simpler to control, more trouble free, and gives improved yields of high quality product.

Abstract: A process for the preparation of glyoxal by vapor phase oxidation of ethylene glycol with oxygen over a copper-containing oxidation catalyst at an elevated temperature and in the presence of a phosphorus compound which is volatile under the reaction conditions, the amount of phosphorus (calculated as P) being from 1 to 100 ppm, based on the weight of ethylene glycol.
