    Abstract: A reactor (1) having a vertical longitudinal axis and an inlet (2) for a liquid or liquid/solid feed stream in the upper region of the reactor and an inlet (3) for a gaseous stream in the lower region of the reactor (1), characterized by at least two chambers (4) arranged above one another in the longitudinal direction, where the chambers (4) are separated from one another by liquid-tight bottom plates, each chamber is connected via a liquid overflow (6) to the chamber (4) located immediately underneath and a liquid product stream is taken off via the liquid overflow (6) of the bottommost chamber (4), the gas space (7) above the liquid surface in each chamber (4) is connected to the chamber (4) located immediately above it by one or more guide tubes (8) which opens (each open) into a gas distributor (9) provided with openings for exit of gas below the liquid surface, and each chamber is provided with at least one guide plate (12) which is arranged vertically around each siphon like gas distributor (9) and whose upper end is below the liquid surface and whose lower end is above the liquid-tight bottom plate (5) of the chamber (4) and which divides each chamber (4) into one or more spaces into which gas flows (13) and one or more spaces into which gas does not flow (14), is used for gas/liquid or gas/liquid/solid reactions.

    Abstract: A reactor, used for reactions between liquid/gas, or gases/liquids/solids, and has a vertical longitudinal axis with an educt feed pipe in the upper part of the reactor. Incoming gas (3) enters via an aperture in the base (5), and is distributed via a gas distributor module (9) that consists solely of straight pipes (14, 15). The gas distributor module has no curved or bent pipes. All pipes within the module are cylindrical and of circular cross section. Pipe sections are joined at right angles to each other. Horizontal distributor pipes (15) are at 40-90% of reactor chamber (4) depth.

    IPC: C07D301/12

    Abstract: The present invention relates to an integrated process for the synthesis of propylene oxide, which comprises at least the following steps: (i) dehydrogenation of propane to give a substream T( 0 ) comprising at least propane, propene and hydrogen; (ii) fractionation of the substream T( 0 ) to give at least one gaseous hydrogen-rich substream T( 2 ) and a substream T( 1 ) comprising at least propene and propane; (iii) synthesis of hydrogen peroxide using the substream T( 2 ), giving a substream T ( 4 ) which is rich in hydrogen peroxide and a gaseous substream T( 6 ); (iv) fractionation of the substream T( 1 ) to give at least one propane-rich substream T( 5 ) and at least one propene-rich substream T( 3 ); (v) reaction of the at least one substream T( 3 ) with substream T( 4 ) to give propylene oxide.

    Abstract: Polyamides, oligomers thereof or mixtures thereof, if required with further reaction products, are prepared by reacting aminonitriles or dinitriles and diamines or a mixture containing aminonitrile, dinitrile and diamine, and, if required, further polyamide-forming monomers and/oligomers with water in a reactor ( 1 ) having a vertically oriented longitudinal axis, by a process in which, in the reactor ( 1 ), the reaction product is removed from the bottom and ammonia formed and any further low molecular weight compounds formed and water are taken off via the top ( 2 ), wherein the reactor ( 1 ) has at least two chambers ( 4 ) arranged one on top of the other in the longitudinal direction, the chambers ( 4 ) being separated from one another by liquid-tight trays ( 5 ), each chamber ( 4 ) being connected by a liquid overflow ( 6 ) to the chamber ( 4 ) directly underneath and a liquid product stream being taken off by the liquid overflow ( 6 ) of the lowermost chamber ( 4 ), the gas space ( 7 ) above the liquid level in each chamber ( 4 ) being connected to the chamber ( 4 ) arranged directly above in each case by one or more conduit pipes ( 8 ) which in each case opens or open into a gas distributor ( 9 ) having orifices ( 11 ) for gas exit below the liquid level, and comprising in each case at least one baffle plate ( 12 ) which is arranged vertically around each gas distributor ( 9 ) and whose upper end terminates below the liquid level and whose lower end terminates above the liquid-tight tray ( 5 ) of the chamber ( 4 ) and which separates each chamber ( 4 ) into one or more gassed ( 13 ) and into one or more ungassed ( 14 ) spaces.
