Abstract: Aromatic amines are produced by adiabatic hydrogenation of nitroaromatic compounds in the gas phase on one or more fixed catalysts. The nitroaromatic reactant is passed over the catalyst under pressure and at elevated temperature with hydrogen, water, optionally nitrogen and substantially in the absence of the aromatic amine produced from the nitroaromatic.

Abstract: A reactor and a process for carrying out parallel reactions on solids is described. The reactor comprises at least a sample holder block (1) with a multiplicity of reaction vessels (2a-2k), a heated support structure (3) and a cover (8, 9, 10) sealing all the reaction vessels (2a-2k). The cover (8, 9, 10) contains feed lines (4a-4k) and discharge lines (5a-5k) to each sample vessel (2a-2k). The feed lines (4a-4k) and/or the discharge lines (5a-5k) are joined together by means of feed and discharge channels (7, 8) running crosswise to said lines. The feed and discharge channels (7, 8) end in main fluid feed lines (11) and discharge lines (12).

Abstract: Process for preparing propene oxide, in which a mixture of propene and oxygen or an oxygen-containing gas is reacted at a temperature in the range from 150 to 500° C., in the presence or absence of a catalyst, in a reactor, wherein all or part of the interior of the reactor is lined with inert materials. The inert material used is at least one of the materials of the following group: one or more noble metals of transition group VIII of the Periodic Table, in particular gold, titanium and tantalum, glass, enamel, quartz, ceramic and Teflon. The selectivity to propene oxide is >60%.
