The invention discloses a method for synthesizing primary amine under the catalysis of nano ruthenium, which comprises the steps of enabling an aldehyde compound to react with ammonia water and hydrogen in one step in the presence of a nano ruthenium and HY zeolite molecular sieve catalyst stabilized by PEG functionalized ionic liquid to generate primary amine, and realizing efficient separation of the catalyst and a product through temperature control after the reaction is finished. The catalyst can be recycled for 5 times, and the catalytic activity and the chemical selectivity can be well maintained. The invention has the advantages of simple synthetic route, novel synthetic method, simple and convenient process, high product yield and purity, cheap and easily obtained catalyst, no influence on environment and suitability for industrial production. |
