Abstract: The invention relates to a process for producing phosgene by gas phase reaction of carbon monoxide and chlorine in the presence of a catalyst in a reactor that comprises a plurality of contact tubes arranged parallel to one another, which contact tubes are filled with the catalyst and around which at least one fluid heat transfer medium flows, a feed stream of a mixture of a chlorine input stream and a carbon monoxide input stream being conducted into the contact tubes and reacted to form a phosgene-containing product gas mixture, characterised in that the product gas mixture is discharged from the contact tubes at an outlet end of the contact tubes. The method according to the invention is characterised in that the gas phase reaction is carried out in the reactor such that the position of the highest temperature in a contact tube (hot spot) moves along the longitudinal axis of the contact tube at a predetermined rate of migration, the hot spot having a rate of migration in the longitudinal direction of the contact tubes which is in the range of 1 to 50 mm per day. The invention also relates to a reactor for carrying out the process.

Abstract: The invention relates to a process for producing phosgene by gas-phase reaction of carbon monoxide and chlorine in the presence of a catalyst in a reactor which comprises a plurality of parallel catalyst tubes which are filled with the catalyst and around which at least one fluid heat transfer medium flows, where a feed stream of a mixture of a chlorine input stream and a carbon monoxide input stream is fed into the catalyst tubes and is allowed to react to give a phosgene-comprising product gas mixture, wherein the reaction is carried out at an area load of more than 2.75 kg of phosgene/m2s. The invention also provides a reactor for carrying out the process.

Abstract: A process for obtaining pure aniline contains catalytically hydrogenating nitrobenzene, to obtain a reaction mixture, separating the reaction mixture into a gas phase containing hydrogen and a liquid phase, liquid/liquid phase separating the liquid phase to obtain an aqueous phase and also crude aniline containing water as an organic phase, distillatively pre-purifying the crude aniline by removing the water via an overhead stream of a first distillation column to obtain a first bottom stream, feeding the first bottom stream as a feed stream to a pure column from which a pure aniline stream is taken off at the top and a second bottom stream containing high boilers is taken off, and passing the second bottom stream to incineration, by pumping the second bottom stream through heated pipelines and by adding methanol, ethanol, propanol, and/or acetone to the second bottom stream.
