摘要
研究了催化剂制备条件、助催化剂对负载型Pd/C催化剂性能的影响及氧分压、原料苯胺中硝基苯的加入对苯胺氧化羰基化反应的影响;用X光电子能谱(XPS)、程序升温还原(TPR)和现场红外(IR)表征钯催化剂;根据实验结果提出在Pd/C-NaI催化剂体系、醇介质中,苯胺氧化羰基化可能的反应机理.
The effects of the preparation conditions of Pd/C catalyst and the promoters on the catalytic property have been investigated. The influences of partial oxygen pressure and addition of nitrobenzene on the oxidative carbonylation of aniline to ethyl Nphenyl carbamate also have been tested. The Pd/C catalyst was characterized by XPS, TPR and insitu IR techniques. A possible mechanism of the oxidative carbonylation of aniline catalyzed by Pd/CNaI system in alcohol medium has been proposed.
