The invention relates to a method for producing tri-n-propyl amine (TPA), wherein di-n-propyl amine is reacted in the presence of hydrogen and a copper-containing heterogeneous catalyst. The integrated method for producing TPA comprises the following operations: I) reacting n-propanol with ammonia in a reactor in the presence of an amination catalyst and optionally hydrogen to form a mixture of mono-n-propyl amine, DPA and TPA, II) separating unreacted ammonia, unreacted n-propanol and optionally hydrogen from the reaction product and returning at least the ammonia and propanol into the reactor in I); and separating the n-propyl amine mixture by distillation and separating the TPAs, III) reacting the DPAs resulting from the separation by distillation in II) in a reactor in the presence of hydrogen and a copper-containing heterogeneous catalyst to form TPA, and IV) feeding the reaction product from III) into the operation II).
