Abstract: New dicarboxylic Gemini surfactant Na-DDEDTA was synthesized from dehydroabietylamine and EDTAA. Its structure was characterized by IR, 1H NMR and 13C NMR spectroscopy. Its surface properties were investigated. Compared with conventional surfactant Na-DMA, Na-DDEDTA has lower CCMC and surface tension with 0.11 mmol/L and 33.6 mN/m, respectively. They have equivalent emulsification ability,but Na-DDEDTA has lower foam properties than Na-DMA. Rosin-based Gemini surfactant is a good green chemicals.
