At the end of the reaction time, the hydrogen pressure is released, filtered off from the catalyst and the product separated by distillation from the solvent.
  • the disadvantage of the process described is that it requires the use of very large amounts of the described Raney catalysts.
  • the lowest amount of catalyst described is 12.3 wt .-% of dry catalyst, based on the weight of tetra-N, N, N ', N' - (2-cyanoethyl) -1, 4-diaminobutane used. In further examples, up to 51.8% by weight of dry catalyst is used.

This hinders the efficient and economical implementation of the process and makes desirable a process that provides equally good product quality using smaller amounts of catalyst. - -

  • tetra-N, N, N ', N' - (3-aminopropyl) -l, 4-diaminobutane can be prepared in high purity with significantly less use of catalyst if the solution of tetra-N, N, N ', N' - (2-cyanoethyl) -l, 4-diaminobutane is metered under hydrogenating conditions to a mixture of Raney catalyst, solvent, ammonia and hydrogen continuously and to the extent consumed by the reaction.

  • a sufficient amount of hydrogen is usually achieved by pressurizing the hydrogen under pressure.
  • the hydrogen is initially introduced under pressure into the reactor before the beginning of the reaction. Preference is given to hydrogen under a pressure of 10 to 200 bar, more preferably under a pressure of 50 to 150 bar.
  • the pressure in the reactor is further conditioned by the presence of ammonia.
  • Ammonia serves to control the selectivity of the hydrogenation in such a way that primary amines prefer to form.
  • secondary and tertiary amines are formed as by-products of the reaction.
  • the molar ratio between ammonia and nitrile groups in the educt should be between 0.25 and 2 mol of ammonia per mole of nitrile group, preferably between 0.65 and 1.25.
  • additives may also serve to increase the selectivity of the reaction for primary amines.
  • Suitable examples are basic additives such as sodium hydroxide or potassium hydroxide or calcium oxide.
  • the temperature of the reaction is adjusted to values of 60 to 150 ° C., preferably to values of 80 to 120 ° C.
  • the hydrogenation is carried out in the presence of a suitable catalyst.

  • Raney catalysts such as Raney nickel or Raney cobalt. These catalysts are known in the art and commercially available from several manufacturers.
  • Raney Nickel and Raney Cobalt are alloys of nickel or cobalt with aluminum. They may contain additions of other metals such as chromium or iron to increase their activity or selectivity. Especially the addition of chromium is advantageous for a high activity in the hydrogenation of nitriles.
  • Raney catalysts are often supplied as an aqueous suspension.
  • the catalyst can be used either moist with water or else the water of the delivery form - - Is replaced by washing with a solvent.
  • Suitable solvents are the abovementioned solvents which can also be used for pumping in the nitrile.
  • the optionally washed catalyst is introduced into the reactor together with solvent, hydrogen and ammonia and stirred under the reaction conditions.
  • the amount of catalyst used is initially dependent on the geometry and handling of the reactor used. In addition, it depends on the amount of substrate to be hydrogenated. Surprisingly, it has now been found that the amount of catalyst required can be reduced to about half that of the prior art, whereby the selectivity and activity of the catalyst is not reduced.
  • WO95 / 2008 and EP-A 707 611 describe the use of from 12 to 50% by weight of the educt of dry catalyst as necessary. According to the inventive method already 5-8 wt .-% of the reactant dry catalyst to complete a reaction of the nitrile of formula (III) and (IV) with almost complete selectivity in favor of the amines of formula (I) and (II ) to ensure.
  • the contents of the reactor must be thoroughly mixed so that both sufficient hydrogen is introduced into the reaction mixture and the catalyst is sufficiently fluidized in order to be able to interact with the starting material.
  • stirring devices in the reactor are suitable.
  • the reaction is started by pumping the melt, the solution or the suspension of the educt against the hydrogen pressure into the reactor.
  • the reaction occurs spontaneously after the dropwise addition of the educt.
  • the reaction time is largely determined by the duration of the pumping process. Usually is pumped in a period of 30 min to 24 h, preferably within 1 h to 8 h. After the end of the pumping process, continued uptake of hydrogen may occur due to the not yet completely completed reaction. After the end of the hydrogen uptake, the reaction is complete. Typical post-reaction times are between 5 minutes and 4 hours.
  • the catalyst used is filtered off from the reaction mixture after the reaction. This can be done via a filter unit outside the reactor or through filter cartridges and a riser inside the boiler. Thus, the catalyst can either be supplied to a suitable disposal or reuse. For reuse, the catalyst may either remain in the reactor and be reused immediately, or it may be reactivated prior to next use. For reactivation, the catalyst can be washed, for example, with an aqueous solution of NaOH or KOH at elevated temperature and washed with water until the effluent solution is almost neutral. - -
