Abstract:

Research progress of preparing meta-xylenediamine by hydrogenation with catalyst from isophthalonitrile was summarized. The improvement of catalyst was reviewed. The influences of reaction conditions，including solvent，initial concentration of materials，reaction inhibitors，reaction pressure and reaction temperature were discussed.The development of reaction  flowsheet and the following separation process was introduced. The basic study of thermodynamic properties of isophthalonitrile and meta-xylenediamine，reaction mechanism and reaction kinetics，and the improvement of reaction flowsheet are the focus of further research.
