Abstract: A method for refining iron oxide that comprises calcining the iron oxide at 700-1200 deg C, is new. Independent claims are included for: (a) iron oxide obtained by the process, containing less than 400 ppm residual chloride; (b) a catalyst prepared using iron oxide refined by calcination; and (c) the dehydration of ethylbenzene to styrene at 450-700 deg C and 0.1-5 bar, using a catalyst as in prepared in (b).

Abstract: Production of maleic anhydride by gas-phase oxidation of C4+ hydrocarbons with oxygen in the presence of a volatile phosphorus compound and a heterogeneous vanadium/phosphorus/oxygen catalyst comprises performing the oxidation in a shell-and-tube reactor comprising at least two sequential cooled reaction zones, in which the first zone is at 350-450 deg C, the second and subsequent zones are at 350-480 and the temperature difference between the hottest and coolest zones is at least 2 deg C. An Independent claim is also included for apparatus for carrying out the process, comprising: a unit for the metered supply of hydrocarbon, oxygen-containing gas and optionally the phosphorus compound; a shell-and-tube reactor comprising at least two sequential cooled reaction zones with independent temperature control; and a unit for separating maleic anhydride and optionally oxygenated hydrocarbon by-products.

Abstract: Continuous gas phase partial oxidn. of an organic cpd. (I) with heterogeneous catalyst in an oxidn. reactor uses a charge gas mixt. contg. (I) O2 and an inert diluent gas (II), which consists partly of combustible gases (IIA). The novelty is that the (IIA) fraction of (II) in the prod. gas stream leaving the oxidn. reactor is not recycled to partial oxidn. but used in another chemical reaction.

Abstract: In a tube bundle reactor for carrying out catalytic organic reactions in the gas phase, comprising reaction tubes (A) arranged between tubesheets (B), the reaction tubes have an inside diameter ranging from 0.5 to 3 cm, the ratio of reaction tube length to inside diameter ranges from 2 to 10, and the reaction tubes (A) are surrounded by a fluid heat transport medium flowing in the crosswise direction; said tube bundle reactor is useful in particular in exothermic organic reactions.

Abstract: Linear - trans - quinacridone - quinone and its 2 : 9-dihalo- and 2 : 9-dialkyl-derivatives are reduced using as reducing agents iron, copper, aluminium, nickel, zinc or an alloy or a mixture of the same in finely-divided form in the presence of (a) aqueous-alcoholic alkali metal hydroxide solution, (b) fused aluminium chloride, or (c) a mineral acid, any dihydroquinacridone obtained being subsequently oxidized. The use of copper or a copper alloy in the presence of a mineral acid is limited to the reduction of the unsubstituted quinacridonequinone. The products obtained are the corresponding linear-trans-quinacridones except when copper or a copper alloy and a mineral acid are used when the product is linear-trans-6-hydroxy-quinacridone. The invention also comprises linear-trans-6-hydroxy-quinacridone. Examples are given. Specifications 828,051, 828,052, 871,976, 896,803 and 911,881 are referred to.
