  • Patent number: 8466322
    Abstract: Process for preparing tri-n-propylamine (TPA), wherein di-n-propylamine (DPA) is reacted in the presence of hydrogen and a copper-comprising heterogeneous catalyst. An integrated process for preparing TPA, which comprises the following operations: I) reaction of n-propanol with ammonia in a reactor in the presence of an amination catalyst and optionally hydrogen to form a mixture of mono-n-propylamine, DPA and TPA, II) separation of unreacted ammonia, unreacted n-propanol and possibly hydrogen from the reaction product mixture and recirculation of at least the ammonia and propanol to the reactor in I) and also separation of the n-propylamine mixture by distillation and isolation of the TPA, III) reaction of the DPA obtained in the separation by distillation in II) in a reactor in the presence of hydrogen and a copper-comprising heterogeneous catalyst to form TPA and IV) feeding of the reactor output from III) to operation II).
