摘要
介绍了硝基苯法制对氨基二苯胺合成工艺及原理,分析了制备工艺中有机溶剂、碱的选择,温度、水分的控制,加氢催化剂、反应器的选择等的研究进展,评述了硝基苯法的改进——碳酰苯胺法制对氨基二苯胺工艺,论述了该工艺的优点。
The preparation of p-aminodiphenylamine by the nitrobenzene process is reviewed. The research progress of organic solvent and bases, control of temperature and water content, hydrogenation catalytst and reactor is summarized. The advantage of preparation of p-aminodiphenylamine by the carbanilide process is discussed.
