Use | organic synthesis intermediates, used in the production of drugs, dyes, spices. |
production method | is obtained by reacting aniline with benzoic acid. The dried benzoic acid and the freshly distilled aniline were reacted at 180-190 °c for 2H and then the temperature was increased to 225 °c. The water was initially distilled off during the reaction, followed by distillation of the aniline, and finally all the fractions were distilled off. The fraction distilled after 255 ° C. Was cooled and solidified, and ground to obtain a purple-gray crude product. The crude product was washed with dilute hydrochloric acid to remove the remaining aniline and washed with water followed by additional sodium hydroxide solution to remove the remaining benzoic acid. Finally, it was washed with water, filtered, dried and recrystallized from ethanol to give a refined product. |
