[Synthesis and characterization of citric acid mono-polyethyleneoxide nonyl phenyl ether amber diehylene glycoldinitrate diglycollic amide].
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 1866.90 cm(-1) and 1781.08 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 1736.14 cm(-1) is attributable to the stretching vibration of C==O in ester, and that at 1642.39 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.
