    摘要： 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.

    摘要： The invention relates to a multistage process for the continuous preparation of organic, distillable polyisocyanates, preferably diisocyanates, particularly preferably aliphatic or cycloaliphatic diisocyanates, by reaction of the corresponding organic polyamines with carbonic acid derivatives and alcohols to form low molecular weight monomeric polyurethanes and thermal dissociation of the latter, in which the polyisocyanates produced and unusable residues are separated off at particular stages of the reaction and reusable by-products and intermediates are recirculated to preceding stages.

    摘要： Olefins having at least 6 carbon atoms are bydroformylated in the presence of a homogenous catalyst in a continuous process in which a) a vertical tall cylindrical reactor (1) whose interior space is divided by means of internals (2). into at least two reaction chambers which extend essentially in the longitudinal direction of the reactor is used, b) at least one olefin is introduced into the reactor together with synthesis gas at the lower end of the first reaction chamber, c) a partially reacted reaction mixture is conveyed from the upper end of a reaction chamber to the lower end of a next reaction chamber; and d) the hydroformylated olefin is taken off at the upper end of the last reaction chamber. The process allows a high conversion at a given reactor volume.

    摘要： In a process for preparing essentially unbranched oligomers of alkenes having from 4 to 6 carbon atoms starting from the alkenes or a hydrocarbon stream comprising such alkenes over a nickel-containing heterogeneous catalyst in an adiabatically operated reactor at from 20 to 300° C. and pressures of from 1 to 100 bar, a first substream of the output from the reactor is worked up to isolate the oligomers and the second substream is recirculated together with fresh alkene or a fresh hydrocarbon stream comprising such alkenes to the reactor.
