| Abstract: | Modified Raney Ni catalysts were used for synthesis of m xylenediamine (m XDA) from isophthalonitrile(IPN) by hydrogenation,and effects of solvent,temperature,pressure and amount of catalyst were investigated.When mixture of methanol and toluene (V/V=1∶2) was used as solvent,conversion of IPN was nearly 100% and yield of m XDA achieved 97% at m(mixed solvent)∶m(IPN)=3∶1,reaction temperature 343 K,pressure 6 0-7 0 MPa and weight ratio of catalyst to IPN 1∶9.The deactivated catalyst after regeneration can regain original activity and selectivity. |
