摘　　要：由柠檬酸出发,经过转化制备柠檬酸酐,与壬基酚聚氧乙烯醚反应制备柠檬酸壬基酚聚氧乙烯醚单酯,再与二乙醇胺反应合成了一种具有防锈、润滑双重性能的水基合成切削液新型添加剂-柠檬酸壬基酚聚氧乙烯醚单酯二乙醇酰胺。采用红外光谱法对原料、中间体及最终产物进行了测试。根据1736.14cm-1酯中CO双键伸缩振动的特征吸收峰,1642.39cm-1酰胺中CO双键伸缩振动的吸收峰,可知所得到的产物为柠檬酸壬基酚聚氧乙烯醚单酯二乙醇酰胺,说明所采用的合成的工艺路线是可行的。In the present paper, citric anhydride was made using citric acid. The citric acid mono-polyethyleneoxide nonyl phenyl ether was synthesized by using citric anhydride and polyethyleneoxide nonyl phenyl ether. Finally, the citric acid mono-polyethyleneoxide nonyl phenyl ether amber diehylene glycol dinitrate diglycollic amide was synthesized by using diethanolamine. The raw material, intermediate and product were characterized by IR. The two absorption peaks at 1 866.90 cm^-1 and 1 781.08 cm^-1 respectively are both strong, with the latter stronger than the former. It was indicated that citric acid had changed into citric anhydride. The absorption peak at 1 736.14 cm^-1 is attributable to the stretching vibration of C=O in ester, and that at 1 642. 39 cm^-1 is attributable to the stretching vibration of C=O in acidamide. It was indicated that the product was citric acid mono-polyethyleneoxide nonyl phenyl ether amber diehylene glycol dinitrate diglycollic amide. So, the synthesis process conditions were right according to the IR data.
