Production method | is obtained by chlorination of salicylic acid. The salicylic acid was dissolved in glacial acetic acid, the temperature was controlled at 8-20 ℃, and the chlorine was stirred for about 8h. After chlorination, continue the reaction for 1h. Cold to 8-10 ℃, filtration, pickling, washing, drying to obtain the finished product. |
