Abstract：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 CO in ester, and that at 1 642.39 cm-1 is attributable to the stretching vibration of CO 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.
