- Abstract: 本文以 3- 氯代苯酐为原料合成 2- 苯甲酰基 -3- 氯苯甲酸粗品，然后 在乙酸乙酯中精制，得到的 2- 苯甲酰基 -3- 氯苯甲酸产品含量为 99.24%。采 用差示扫描量热法（DSC）、红外光谱 （IR）、质谱（MS）和核磁共振氢谱（HNMR） 等技术，对 2- 苯甲酰基 -3- 氯苯甲酸进行了表征。
- In this paper, 2-benzoyl-3-chlorobenzoic acid was synthesized from 3-chlorophthalic anhydride and refined in ethyl acetate. The content of 2-benzoyl- 3-chlorobenzoic acid was 99.24%. Differential scanning calorimetry (DSC), infrared spectroscopy (IR), mass spectrometry (MS) and nuclear magnetic resonance (HNMR) were used to characterize 2-benzoyl-3-chlorobenzoic acid.
