摘要： The present application relates to a method for photochlorination, and specifically to photochlorination by a photochemical reaction of an aromatic compound with gaseous chlorine so as to prepare a trichloromethyl-substituted benzene, and to a method using bis-(trichloromethyl)-benzene as the trichloromethyl-substituted benzene to prepare by further reaction bis-(chloroformyl)-benzene. Through the control of temperature, illuminance and consumption of gaseous chlorine, the method of this application can greatly improve the purity of trichloromethyl-substituted benzene and further prepare polymer-grade bis-(chloroformyl)-benzene with low cost. The present application also relates to a method for purifying trichloromethyl-substituted benzene, and specifically to a method for purifying trichloromethyl-substituted benzene via molecular distillation. The present application further relates to a photochlorination reactor for use in photochlorination reactions (such as those of the present application).

摘要： The present invention discloses a method for producing 4-aminodiphenylamine by reacting nitrobenzene with a aniline in the presence of complex base catalyst for condensation and complex powdery catalyst for hydrogenation, which comprises the steps of condensation, separation, hydrogenation, separation II and refining sequentially. The method of the present invention can be carried out continuously. By using the complex base catalyst for the condensation, followed being separated and recycling before the hydrogenation, the problem of heat-sensitive decomposition of the complex base catalyst during the hydrogenation procedure can be avoided. Accordingly, the choice of the hydrogenation catalyst is increased, and lower-cost hydrogenation catalysts can be used. Meanwhile, the apparatus can be selected easily and the industrialization can be achieved simply. The complex base catalyst according to the invention is cheaper. The catalystic activity of the catalyst is high and the condition of the reaction is gentle. Additionally, the complex base catalyst is suitable to a wide range of water content. Accordingly the amount of the by-product is decreased, and the conversion and the selectivity can be increased. The labour intensity of the process control is low. Moreover, corrodible liquid is not generated and the environmental pollution can be reduced. The content of 4aminodiphenylamine reaches 99% (by weigh), and yield of the industrial- scale production is greater than 95%.
摘要翻译：本发明公开了一种生产4-氨基二苯胺的方法，该方法包括硝基苯与苯胺在复合碱催化剂存在下反应生成缩合物和复合粉状加氢催化剂，包括缩合，分离，加氢，分离II和精馏步骤。本发明的方法可以连续进行。通过使用用于缩合的复合碱催化剂，随后在加氢之前分离和再循环，可以避免氢化过程中复合碱催化剂热敏分解的问题。因此，氢化催化剂的选择增加，并且可以使用低成本的氢化催化剂。同时，该设备可以轻松选择，简单实现产业化。根据本发明的复合碱催化剂更便宜。催化剂的催化活性高，反应条件温和。另外，复合碱催化剂适用于各种含水量。因此，副产物的量减少，并且转化率和选择性可以增加。过程控制的劳动强度低。而且，不会产生可腐蚀液体，并且可以减少环境污染。 4-氨基二苯胺含量达到99％（重量），工业规模生产收率大于95％。
