摘要：
PURPOSE: A process for preparing the title compound by reaction of phenylurea capable of easily manufacturing from urea and aniline with nitrobenzene using an alkali metal base such as sodium hydroxide or an alkali earth metal base is provided, which can prevent generation of ortho compounds such as 2-NDPA and phenazine and azoxybenzene as byproducts by passing oxygen and air through a reaction atmosphere. The process can also generate no harmful material such as chlorine and reduce an amount of waste. CONSTITUTION: In a process for manufacturing 4-nitrodiphenylamine and 4-nitroaniline using an aromatic hydrogen nucleophilic reaction, phenylurea and nitrobenzene are reacted at 20 to 150deg.C in the presence of a base and a polar organic solvent. The base is used in an amount of 1 to 10 times by molar ratio based on the phenylurea and selected from sodium hydroxide, sodium hydride, potassium hydride, potassium hydroxide, t-butoxy potassium and sodium amide.
摘要（中）：
目的：提供一种使用碱金属碱如氢氧化钠或碱土金属碱使能够容易地从尿素和苯胺与硝基苯制备的苯脲反应制备标题化合物的方法，其可以防止产生诸如 2-NDPA和吩嗪和偶氮氧苯作为副产物，通过氧气和空气通过反应气氛。 该方法也不会产生有害物质如氯，并减少浪费。 构成：在使用芳香族氢亲核反应的4-硝基二苯胺和4-硝基苯胺的制造方法中，在碱和极性有机溶剂的存在下，使苯脲和硝基苯在20〜150℃下反应。 碱的用量为1〜10倍，基于苯脲，选自氢氧化钠，氢化钠，氢化钾，氢氧化钾，叔丁氧基钾和氨基钠。
