Abstract: Production of phthalic anhydride from o-xylene by 2-stage oxidation with recycle of unreacted xylene from the first stage comprises removing toluene from the xylene recycle stream by distillation. Production of phthalic anhydride comprises: (1) partially oxidizing o-xylene in the liquid phase with oxygen or a mixture of oxygen and an inert gas in the presence of a catalyst; (2) distilling the partially oxidized mixture to separate a fraction comprising unreacted xylene; (3) distilling the xylene fraction to remove toluene; (4) recycling the xylene fraction to step (a); and (5) oxidizing the xylene-depleted partially oxidized mixture in the gas phase to produce phthalic anhydride.

Abstract: The invention relates to a method for producing shell catalysts for the catalytic vapor-phase oxidation of aromatic carboxylic acids and/or carboxylic acid anhydrides comprised of a supporting core and of catalytically active metal oxides which are deposited in a shell-shaped manner on said supporting core. The inventive catalysts are obtained by spraying an aqueous active mass suspension, said suspension containing the active metal oxides, at higher temperatures onto the hot supporting material which has a temperature ranging from 50 to 450° C. The aqueous active mass suspension contains 1 to 10 wt. %, with regard to the solid content of the active mass suspension, a binding agent comprised of A) a polymerizate obtained by radical polymerization, containing 5 to 100 wt. % of monomers (a) in the form of ethylenically unsaturated acid anhydrides or ethylenically unsaturated dicarboxylic acids whose carboxyl groups can form an anhydride and containing 0 to 95 wt. % monoethylenically unsaturated monomers (b) with the provision that the monomers (a) and (b) comprise, on average, a maximum of 6 carbon atoms which are not functionalized with groups containing oxygen, and of B) an alkanolamine having at least 2 OH groups, a maximum of 2 nitrogen atoms and a maximum of 8 C-atoms, whereby the weight ratio A:B ranges from 1:0.05 to 1:1.

Abstract: In a nickel-catalysed method for the oligomerization of 4-8C alkenes in a series of 2 or more reactors operating under adiabatic conditions, the feed stream is split and the part-streams are fed into at least 2 of the reactors with the addition of fresh feed so that the temperature in any reactor is not more than 20[deg]C above that in any of the other reactors. A method for the production of oligomers of 4-8C alkenes from a hydrocarbon feed stream containing such alkenes, on a nickel-containing heterogeneous catalyst in a series of 2 or more reactors operating under adiabatic conditions at 30-280[deg]C and 1-300 bar, where: (a) the feed stream is introduced into reaction zone 1 at a temperature T1, (b) the temperature increases in each zone, and (c) if this increase is more than T1 + 20[deg]C, the temperature is adjusted to within the range T1 +- 20[deg]C before the mixture is fed into the next zone. In this method, the feed stream is split and the part-streams are fed into at least two of the reactors with the addition of fresh feed so that the temperature in any one reactor is not more than 20[deg]C above that in any of the other reactors.
