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.

METHOD FOR THE SYNTHESIS OF HIGH PURITY PRIMARY DIAMINES AND/OR TRIAMINES

The present invention relates to a process for the preparation of primary di- and/or triamines of high purity from nitriles which can themselves originate from dimer and/or trimer acids. This process comprises a stage of ammoniation of the acid functional groups and a stage of hydrogenation of the nitrile functional groups to give primary amine functional groups and does not require additional purification stage(s).
