摘要
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。
2-Benzoyl-3-chlorobenzoic acid was synthesized by using 3-chlorophthalic anhydride as raw materials.Differential scanning calorimetry(DSC),infrared spectroscopy(IR),mass spectrometry(MS),nuclear magnetic resonance NMR(HNMR) technology were used to the structure characterization of 2-benzoyl-3-chloride benzoic acid.
