| 摘 要： | 本文研究了80℃常压CO2-H2O体系中,锌粉选择还原硝基苯生成苯基羟胺的反应.硝基苯的转化率随反应时间的延长而增加,同时苯基羟胺和苯胺的产率也增大,但苯基羟胺的选择性基本不变.通过实验证实苯胺是通过原料硝基苯和苯基羟胺还原而得到的.

| Abstract: | Nitrobenzene is selectively reduced to aniline using Zn dust at 80℃ in normal CO2-H2O system.With prolonging the reaction time,the conversion of nitrobenzene increases,and both the yield of N-phenylhydroxylamine and aniline increases,but the selectivity of N-phenylhydroxylamine almost constant.The results demonstrate that aniline is obtained by two approaches:nitrobenzene or N-phenylhydroxylamine is as material. |
