聚席夫碱钯（Ⅱ）配合物对芳香族硝基化合物加氢反应的催化性能

Catalytic Activities of Poly-Schiff Base Pd (Ⅱ)Complexes in Hydrogenation of Aromatic Nitro-Compounds

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。

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