Abstract: The invention relates to a method for producing chlorine in a fluidized bed reactor, a gaseous reaction mixture containing hydrogen chloride and oxygen flowing from the bottom to the top of a heterogeneous particulate catalyst that forms a fluidized bed. The invention is characterized in that said fluidized bed comprises insertion elements which divide the fluidized bed into a plurality of horizontal and vertical cells arranged in the fluidized bed reactor, the walls of said cells being permeable to gas and having openings for ensuring the exchange of particles of the heterogeneous particulate catalyst in the vertical direction in the range of between 1 and 100 liter(s)/hour per liter of reactor volume.

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: 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: Solutions of molecular oxygen in liquid hydrocarbons are prepared by bringing a liquid hydrocarbon into contact with molecular oxygen under superatmospheric pressure in a vertical absorption zone, by a process in which (a) a layer of water is maintained at the lower end of the absorption zone, (b) molecular oxygen is passed into the layer of water, (c) a liquid hydrocarbon is fed in above the layer of water, (d) the finely divided molecular oxygen rising from the layer of water is passed upward together with the liquid hydrocarbon at from 0 DEG to 50 DEG C., with thorough mixing in the absorption zone, with the proviso that no cohesive gas phase is formed, and (e) the solution of molecular oxygen in the liquid hydrocarbon is discharged in the upper part of the absorption zone.
