Abstract: The rosin-based sulfonate was synthesized from dehydroabietylamine reacted with maleic anhydride. Its structure was characterized by IR spectroscopy. Its surface-activities were also investigated. Results show that critical micelle concentration (CMC) of DHAAMS is 0.798 mmol/L, the foaming ability is 145 mm, and water-oil separation time can reach 9 min,showing a strong emulsification ability. The strong synergism of DHAAMS with SDS is observed. The optimum synergism is obtained at the mass ratio of 1:3.

Key words: rosin-based, sulfonate, surfactant
