| titleOfInvention | Method of diphenylamine production from aniline catalyzed by fluoroborates |
| abstract | 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 NH4BF4. NH4BF4crystals 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. |
