Abstract: Reaction mixtures which contain cyclohexanol, cyclohexanone and cyclohexyl hydroperoxide and are obtained in the oxidation of cyclohexane with molecular oxygen, or with a gas containing this, in the liquid phase are worked up by a process in which the reaction mixture is hydrogenated in the presence of a noble metal catalyst at elevated temperatures and under superatmospheric pressure, the resulting mixture is treated with an aqueous alkali metal carbonate solution, and cyclohexanol and cyclohexanone are separated off by distillation.

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: Oxygen-containing compounds are prepared by oxidizing a hydrocarbon in the liquid phase with a gas containing molecular oxygen, at elevated temperatures and under superatmospheric pressure, by a continuous process in which the said gas is fed into the liquid reaction mixture, in a downward direction, at several points along the reaction zone via nozzle apertures, so that it emerges at each nozzle aperture with a velocity of from 0.01 to 1 m/sec in an amount of from 0.001 to 10 liters per second per nozzle aperture, and the said reaction mixture is brought into substantially uniform contact with the gas containing molecular oxygen, over the volume of the reaction zone.

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.
