    Abstract: A shell-and-tube reactor is disclosed. Contact tubes are disposed within a cylindrical housing and are secured to tube plates. Gas and liquid phases are received via a feed opening in a lower end cap and discharged via an upper end cap in the housing. A distributor device for a gas phase/liquid phase mixture is disposed below the lowermost tube plate. The distributor device includes a distributor plate and a predistributor. The distributor plate is arranged horizontally within the housing and includes an active area having through-openings and a downward-extending margin, but does not extend over the entire cross section of the housing. The predistributor includes a second distributor plate disposed between the feed opening and the first distributor plate, wherein the second distributor plate includes a second active area with second through-openings and a second downward-extending margin.

    IPC: C07C263/10

    Abstract: The invention relates to a method for producing isocyanates and/or polyisocyanates by reacting the corresponding amines with phosgene optionally in the presence of an inert medium in a reactor (1) wherein a first reactant stream containing the amine is fed to the reactor (1) in liquid form and a second reactant stream containing the phosgene is fed to the reactor in gaseous form. The reactor is a centrifugal reactor (1) which has a packing (9) rotating about a central axis (7) in a housing (13) the first reactant stream and the second reactant stream being fed to the rotating packing (9) in such a manner that the reactant streams are mixed and transported outward by the centrifugal force in the rotating packing (9) wherein the phosgene reacts with the amine due to the mixing in the rotating packing (9) to form the corresponding isocyanate or polyisocyanate.
