  • Patent number: 9725560
    Abstract: The present invention relates to a catalyst for reductive amination-reaction, and uses thereof. The catalyst according to the present invention can show a high amine conversion rate because it can maintain catalytic activity even in the presence of moisture particularly while basically maintaining the balance of dehydrogenation and hydrogenation reactions. Accordingly, the catalyst can be usefully used for preparing a polyetheramine compound through a reductive amination-reaction not only in a continuous preparation process but also in a batch preparation process, irrespective of the existence of moisture.
