Authors investigated the reaction of n-octanol with diethyl amine as a model synthetic experiment of higher amine by the reaction between higher alcohol and lower amine. In the case of copper-chromium oxide as a catalyst, the reaction proceeded at 200300°C for a short time and approx. 30 percent of octyl ethyl amine and 30 percent of octyl diethyl amine were obtained. The copper chromium oxide catalysts were reduced into metallic copper during the reaction. The exchange reaction of alkyl groups proceeded at a lower temperature than that of the dehydration reaction between alcohol and amine. In the case of the metallic copper powder as a catalyst, the higher reaction temperature was required than the case of copper chromium oxide catalyst. The amines obtained were, in every case, mixed amines and solitary tertiary amine could not be synthesized.
