Production method

Add chlorobenzene to an enamel pot to steam the moisture to below 0.03%, add salicylic acid, and evenly pass chlorine to a predetermined amount at 110±2°C. Take a sample and observe the precipitate cooled to 30°C, filter, measure the melting point, and take 167-175°C as qualified to obtain a chlorobenzene solution of 5-chlorosalicylic acid. If the chlorination reaction is carried out under the irradiation of a fluorescent lamp, the chlorine can reach the theoretical amount at 55-80°C. After sampling and testing, the remaining chlorine is removed, cooled, filtered, washed with chlorobenzene, and dried to obtain the finished product.
