Abstract: Preparation of amines(I) by hydrogenation of nitro compounds(II) is carried out in a vertical reactor having length greater than its diameter. At the top is a downwards-directed nozzle supplying starting material and recyled reaction mixture, and an outlet from which the reaction mixture is pumped to the nozzle through an external circuit. The flow of reaction mixture is reversed at the base of the reactor.

Abstract: A catalyst comprising nickel on a TiO 2 support is obtainable by coprecipitation of nickel and at least one further metal selected from among Si, Zr, Hf, alkaline earth metals, Y, La and Ce, and optionally at least one dopant metal selected from groups 5 to 11 of the Periodic Table of the Elements, from a solution in which the corresponding metal salts are present onto a particulate TiO 2 support, subsequent drying, calcination and reduction and optionally passivation to give the nickel-containing catalyst. It is used, in particular, for the hydrogenation of nitroaromatic compounds.

Abstract: Liquid organic compounds are hydrogenated by a process in which the hydrogen present in the reactor contains proportions of at least one gas which is inert in the hydrogenation reaction.

Abstract: Production of polyether polyols comprises use of a multi-metal cyanide complex catalyst in a tall cylindrical reactor having a downward facing spray nozzle in the upper reactor portion, through which the educts and reaction mixture are fed and an outlet, preferably in the lower portion of the reactor to recirculate the reaction mixture via an external circuit and equalizing reservoir. A process for the production of polyether polyols (I) by reaction of diols or polyols with ethylene oxide, propylene oxide and/or butylene oxide in the presence of a multi-metal cyanide complex catalyst (II) comprises carrying out the reaction in a tall cylindrical reactor having a downward facing spray nozzle in the upper reactor portion, through which the educts and reaction mixture are fed, and an outlet, preferably in the lower portion of the reactor, through which the reaction mixture is fed by means of a pump through an external circuit via an equalizing reservoir to the spray nozzle. The external circuit comprises a concentric pipe stretching the entire length of the reactor excluding the reactor ends and contains a heat exchanger integrated within the annulus.

Abstract: Amines are prepared by hydrogenation of the corresponding nitroaromatics in a vertical reactor whose length is greater than its diameter and which has in its upper region a downward-directed jet nozzle via which the reaction mixture and, if desired, part of the starting materials are introduced, has an outlet at any point on the reactor via which the reaction mixture is conveyed in an external circuit by means of a transport device back to the jet nozzle and has a flow reversal in its lower region, wherein at least part of the hydrogen and/or nitroaromatic starting materials used is fed into the liquid phase of the reactor in such a way that they travel upward in the liquid phase.

Abstract: The production of amines (I) by hydrogenation of nitro compounds (II), carried out in a vertical reactor with length greater than its diameter. It has a spray at the top for introducing educts and reaction mixture and an outlet through which the reaction mixture is pumped into an external cycle. The circulation is reversed in the lower zone of the reactor.
