    Abstract: The invention relates to a reactor (1) in the form of a horizontal cylinder for carrying out autothermal gas phase dehydrogenbation of a hydrocarbon-containing gas flow (2) by means of an oxygen-containing gas flow (3), with a reaction mixture being obtained, on a heterogeneous catalyst in the form of a monolith (4), characterized in that the interior of the reactor (1) is divided by a detachable cylindrical or prismatic housing G, which is disposed in the longitudinal direction of the reactor (1), gastight in the circumferential direction and open at both end faces thereof, into an inner area A, having one or a plurality of catalytically active zones (5), in which are provided a packing of monoliths (4) stacked on, adjacent, and above one another, and, in front of each catalytically active zone (5), a mixing zone (6) having fixed installations, and an outer area B disposed coaxially to the inner area A.

    Abstract: A process for extractively removing homogeneously dissolved catalysts from a reaction effluent of a hydrocyanation of unsaturated mononitriles to dinitriles with a hydrocarbon H, including performing the steps of a) concentrating the reaction effluent before step b) by distillation at pressures of from 0.1 to 5000 mbar and temperatures of from 10 to 150° C., b) adding a hydrocarbon H to the concentrated reaction effluent to obtain a stream I, and c) feeding stream I, without prior separation of the liquid phases, into an extraction apparatus and extracting it at a temperature T with the hydrocarbon H to obtain a stream II comprising the hydrocarbon H enriched with the catalyst and a stream III having a low catalyst content.

    Abstract: Preparation of nickel(0)-phosphorus ligand complexes (Q) containing at least a nickel(0) as central atom and at least a ligand containing phosphorus comprises reacting a nickel(II) compound with a reducing agent in the presence of the ligand to obtain a reaction mixture and extracting the obtained reaction mixture by adding at least a dinitrile, at least a hydrocarbon and at least two immiscible phases. Preparation of nickel(0)-phosphorus ligand complexes (Q) containing at least a nickel(0) as central atom and at least a ligand containing phosphorus comprises reacting a nickel(II) compound with a reducing agent in the presence of the ligand to obtain a reaction mixture, and extracting the obtained reaction mixture by adding at least a dinitrile, at least a hydrocarbon and at least two immiscible phases, where: the amount of nickel(0) content in the reaction mixture is at most 1.3 wt.%; the molar ratio of: the reducing agent to the nickel(II) compound is 1:1-1000:1, which is calculated as the molar ratio of the redox equivalent, and the ligand containing phosphorus to the nickel(II) compound is at most 30:1, which is calculated as the molar ratio of phosphorus and nickel atoms. Independent claims are included for: (1) a mixture comprising (Q), obtained by the above process; and (2) a method for the isomerization of unsaturated nitrile to linear unsaturated nitrile using (Q) as catalyst, which is regenerated by circulation method.
