Study on the synthesis of m-xylylenediamine

Using isophthalonitrile as raw mater ial and Raney nickel as catalyst, catalytic hydrogenation to m-xylylenediamine was carried out, and the influence of various factors on the reaction results was discussed: purity of isophthalonitrile raw material, catalyst, reaction The influence of additives,reaction temperature, reaction pressure and reaction solvent on the catalytic hydrogenation reaction. The optimal control conditions for the catalytic hydrogenation of isophthalonitrile to m-xylylenediamine were proposed. It is pointed out that the purification of the starting material isophthalonitrile and the study of the catalyst are the research focus of the industrialization of meta-xylylenediamine to the catalytic hydrogenation of phthalonitrile.
