摘要： The invention concerns a method of diphenylamine production from aniline by a continuous procedure in liquid phase catalysed by thermolabile compounds of fluorine with boron which convert under conditions of diphenylamine formation from aniline to NH 4 BF 4 . NH 4 BF 4 crystals arising in the reaction medium of the reactor are maintained in uplift during a time,which is at least so long as the dwell time of aniline in the reactor. The maintaining in uplift is ensured by circulation stirring of the reaction mixture with a stirrer of minimum volume-rate of 0.1-multiple ofthe reaction mixture volume per hourand it is realized by mechanical stirring providing turbulent axial-radial flow of the reaction mixture in the reactor. An input overheated water steam is supplied countercurrentlyto the catalyst into the reactor withpressure higher than the sum of saturated vapour tension of the reaction mixture at the working temperature and hydrostatic pressure of the reaction mixture. Aninput reactant aniline is supplied into the reactor countercurrently to the catalyst input with such speed which ensures at least the same residence time of the catalyst in uplift as is the residence time of aniline in the reactor.
摘要翻译：本发明涉及一种由苯胺生产二苯胺的方法，该方法是通过氟与硼的热不稳定化合物在由二苯胺形成的苯胺转化为NH4BF4的条件下催化的液相中连续进行的。在反应器的反应介质中产生的NH4BF4晶体在一段时间内保持升高，其至少等于苯胺在反应器中的停留时间。通过循环搅拌反应混合物，用搅拌器循环搅拌，保证反应混合物的最小体积速率为每小时反应混合物体积的0.1倍，并通过机械搅拌实现反应混合物在反应器中的湍流轴向 - 径向流动。输入过热水蒸汽逆流向催化剂供给反应器，其压力高于反应混合物在工作温度和反应混合物的静水压力下的饱和蒸汽张力的总和。将输入反应物苯胺以这样的速度与催化剂输入端逆流供应到反应器中，这确保了催化剂在提升中的停留时间至少相同于苯胺在反应器中的停留时间。
