摘要: 以交联聚席夫碱钯的配合物作为催化剂,对芳香族硝基化合物催化加氢性能进行了研究。该催化剂在常温、常压下可使硝基苯100%催化氢化为苯胺。对某些芳香族硝基化合物转化为相应胺的产率也可达90%以上。此催化剂性能稳定,重复使用80次仍具有一定催化活性。

Abstract: The polyschiff base Pd(Ⅰ)complexes were used as catalysts to hydrogenate aromatic nitrocompounds at room temperature and ordinary pressure. Nitrobenzene was hydrogenated quantitatively,the conversion for most other aromatic nitrocompounds was also up to 90%. The catalyst is stable,For hydrogenation of nitrobenzene after reusing around 80 times,the fast rate of taken-up hydrogen remained 25mL/min.The catalyst reused for 10 times has been proved by XPS to be Pd(Ⅰ)complex.

Key words: poly-schiff base-Pd complex, catalytic hydrogenation, aromatic nitrocompound
