| 摘 要： | 以1，5-二氨基葸醌为原料，与苯甲酰氯反应，以苯甲酸甲酯为溶剂，以碳酸钠作缚酸剂，制得1-氨基-5-苯甲酰氨基蒽醌，并对合成工艺进行了优化。优化条件为：n（苯甲酰氯）：n（1，5-二氨基蒽醌）=1．4：1，反应温度140℃，保温2h。在此条件下，目标产物收率比原工艺提高13％。采用熔点测定、红外光谱（IR）、液相色谱（HLPC）进行分析和结构表征。

| Abstract: | l-Amino-5-benzoylaminoanthraquinone was synthesized by reaction of 1,5-diaminoanthraquinone and benzoyl chloride,using methyl benzoate as solvent and sodium carbonate as an acid binding agent.The synthesis optimum process was as follows:the molar ratio of benzoyl chloride and 1,5-diaminoanthraquinone was 1.4:1,the reaction temperature was 140℃,the reaction time was 2 hours.Under the above optimum conditions, the target product yield increased by 13%than the original technology.The product was conformed by melting point、Infrared spectroscopy(IR),high performance liquid chromatography(HLPC)Analysis and structure characterization. |
