Popis: An atom-economic and moderate approach for highly selective one-step catalytic amination of cyclohexene to cyclohexylamine using HZSM-5 with a Si/Al ratio of 38 has been successfully developed in this work. Results showed that 4.3% cyclohexene conversion with 100% selectivity to cyclohexylamine was achieved under optimal reaction conditions. The acid strength of the catalyst played an extraordinarily important role in the present amination reaction. The possible catalytic amination mechanism of cyclohexene with NH3 using HZSM-5 has also been suggested. This approach is a promising process for the preparation of cyclohexylamine from one-step amination of cyclohexene employing commercialized HZSM-5 as an effective and regenerable catalyst under relatively mild conditions.
