壳聚糖-钯催化剂用于对硝基苯酚的催化加氢

Pd-Chitosan Catalyst Using in the Catalytic Hydrogenation of p-Nitrophenol

探讨了用于对硝基苯酚加氢的催化剂—Pd -壳聚糖的制备方法和在常温常压下用该催化剂催化对硝基苯酚加氢反应制对氨基苯酚 (PAP)的合成路线 ,并探讨了催化剂制备方法和加氢反应条件对产物收率的影响。在适宜的反应条件下 ,PAP的收率可以达到92 % ,质量标准符合医药级。通过与其他用于制PAP的催化剂相比较 ,Pd -壳聚糖催化剂具有良好的研究与应用前景。

The preparation of p -aminophenol by the catalytic hydrogenation of p -nitrophenol using the catalyst of palladium on chitosan under atmospheric pressure and at room temperature has been studied.The effects of the catalysts in different solvents on the yield of PAP was discussed.Under the suitable reaction condition,the yield of PAP was 92%.The standard of synthetic PAP follows medical rawmaterial degree.
