A synthesis of N-ethyl-n-butylamine with simple separation method in a fixed-bed reactor using CuO–NiO–PtO/γ-Al2O3 as the catalyst was proposed and investigated. The present catalytic system gave high activity and good selectivity, and the reaction conditions such as temperature and liquid hourly space velocity were optimized. Since no water was generated, the protocol proved to be easy to separate, and N-ethyl-n-butylamine was collected at 110 °C by distillation. The yield and the purity were 60.7 and 99.5 %, respectively.
