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.

Nitrobenzene is selectively reduced to aniline using Zn dust at 80℃ in normal CO2-H20 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.
