Method for producing isoamyl amine

The invention discloses a method for producing isoamyl amine. In a gas and solid phase fixed bed reactor loaded with negative load type catalysts, isoamyl alcohol and liquid ammonia are used as raw materials for carrying out hydro-ammonification reaction, products obtained from the reaction are separated by distillation, and isoamyl amine, diisoamyl amine and triisoamyl amine are respectively obtained. The reaction temperature is 150-250 DEG C, the reaction pressure is 0.5-3.0MPa, the liquid air speed is 0.1-0.9h-1, and the mole ratio of the liquid ammonia, the isoamyl alcohol and the hydrogen is 0.5-9: 1: 2-5. The use of the method for producing isoamyl amine has the characteristics of low cost, high yield, environment friendliness and the like.
