    摘要: The present invention relates to a process for hydrogenating organic nitriles by means of hydrogen in the presence of a catalyst in a reactor, where the shaped body catalyst is arranged in a fixed bed, wherein the shaped body in the shape of spheres or rods has in each case a diameter 3 mm or less, in the shape of tablets a height of 4 mm or less, and in the case of all other geometries in each case has an equivalent diameter L=1/a′ of 0.70 mm or less, where a′ is the external surface area per unit volume (mms2/mmp3), where: a ′ = A p V p , where Ap is the external surface area of the catalyst particle (mms2) and Vp is the volume of the catalyst particle (mmp3). The present invention further relates to a process for preparing downstream products of isophoronediamine (IPDA) or N,N-dimethylaminopropylamine (DMAPA) from amines prepared according to the invention.

    摘要: 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.
