Synthesis method
Derived from the reaction of aniline and benzoic acid. React dry benzoic acid and freshly steamed aniline at 180-190°C for 2 hours, then increase the temperature to 225°C. At the beginning, water is distilled off during the reaction, then aniline is distilled off, and finally all the fractions are distilled off. The fractions evaporated after 255°C are cooled, solidified, and ground to obtain a purple-grey crude product. The crude product is washed with dilute hydrochloric acid to remove remaining aniline, washed with water and then added with sodium hydroxide solution to remove remaining benzoic acid. Finally, wash with water, filter, dry, and recrystallize with ethanol to obtain a refined finished product.
Purpose
Dye, fragrance and pharmaceutical intermediates.
