Synthesis and Characterization of N-N'-ethylene-bis(1-dodecylsuccinamic acid)

摘要

The present work reports the synthesis of N-N'-ethylene-bis(1-dodecyl succinamic acid),a new anionic gemini surfactant by reacting 2-dodecen-1-ylsuccinic anhydride with ethylene diamine using dichloromethane as solvent.The effect of reaction variables like time and molar ratio of raw materials on anionic content()and yield( wt)has been studied.The study revealed that 2:1 molar ratio of reactants and 6 hr duration was optimum for yielding gemini surfactant with a maximum anionic content of 49.4.The structure of synthesized anionic gemini surfactant was characterized by FT-IR,~1H NMR and ~(13)C NMR spectral studies.
