Abstract:
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.
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。
