Method of production:

It is obtained by the reaction of aniline with benzoic acid. The dried benzoic acid and freshly evaporated aniline were reacted at 180-190 ℃ for 2h, and then the temperature was increased to 225 ℃. At the beginning, water is evaporated in the reaction process, then aniline is evaporated, and finally all the fractions are evaporated. The fraction evaporated after 255 ℃ is cooled, solidified and ground to obtain purple gray crude product. The crude product is washed with dilute hydrochloric acid to remove the remaining aniline, washed with water, and then added with sodium hydroxide solution to remove the remaining benzoic acid. Finally, the refined product is obtained by washing, filtering, drying and recrystallization with ethanol.
