苯胺氧化羰基化催化体系研究

The Study of Catalytic System for the Oxidative Carbonylation of Aniline

考察了催化剂Pd/C的制备、回收使用及助催剂的情况, 并比较了Pd/C反应前后的XPS谱. 通过实验, 还发现PdCl2 和PdO 同Pd/C相比有相同的催化活性. 最后, 建议了氧化羰基化的机理.

The preparation of catalyst Pd/C and its reuse information and the promoter have been studied,the XPS spectrums of catalyst before and after reaction are compared with each other. PdCl 2 and PdO are found that have the same catalytic activity as that of Pd/C.At last,we propose the mechanism of aniline oxidative carbonylation.
