Azelanitrile preparation method

The invention relates to an azelanitrile preparation method, which comprises: (1) dissolving glutaraldehyde in a solvent, adding a condensation catalyst and an optional cocatalyst, adding cyanoaceticacid in batches to maintain the temperature of the reaction solution of not more than 40 DEG C, and carrying out a condensation reaction, wherein a molar ratio of the glutaraldehyde to the cyanoaceticacid is 1:2; and (2) further adding a palladium carbon catalyst (Pd/C) to the condensation reaction liquid obtained in the step (1), introducing hydrogen gas, maintaining the pressure, heating, and carrying out a decarboxylation and hydrogenation reaction to obtain azelanitrile, wherein the hydrogen pressure is 3.0-4.0 MPa. According to the present invention, the method can perform the reaction by using the one-step method so as to eliminate the separation and purification process of the intermediate product, such that the reaction process is simple, and the cost is low.
