Abstract: Co-Ni-Zn-Fe/HZSM-5 catalyst was prepared by the precipitation - deposition method and used in the reaction of catalytic amination of isobutanol to isobutylamine. Investigation of the type of carrier，proportion of active ingredients determined the most suitable active metals in the catalyst system as 22.5% Co-12.8% Ni-3.0% Zn-1.5% Fe. Under the optimum reaction conditions：pressure 1.2MPa，amino∶alcohol= 8∶1；temperature 185℃；alcohol liquid flow rate of 0.6—0.8h?1，conversion rate of isobutanol reached 98.5%，Byproducts，such as triisobutylamine，were effectively suppressed at the same time，and total selectivity of isobutylamine and diisobutylamine reached 99.8%. The performance of the reaction was greatly improved，providing a new method for efficient production of isobutylamine with higher value of industrial application.
