[0018] Example: 1mmol of 2,5-dicyanofuran, 30mg of Rh / HZSM-5 catalyst with a loading of 5wt%, and 7mL of methanol were added to a 15mL reaction kettle, and the air in the kettle was replaced with hydrogen 10 times. After the temperature was raised to 120° C., hydrogen gas was charged to 2.5 MPa, and stirring was started. If the hydrogen partial pressure drops, replenish it to 2.5MPa. The reaction was completed for 3h and cooled to room temperature. The reaction solution was centrifuged to separate out the catalyst, sampled, and the product was analyzed by liquid chromatography. like figure 1 Shown is the high performance liquid chromatography (HPLC) figure of the reaction solution, wherein the retention time is 11.328min is the raw material 2,5-dinitrile furan, and the retention time is 15.247min is the product 2,5-dimethylaminofuran . A small amount of by-products are diamines and triamines containing multiple furan rings. Using the external standard method to do the wor...
