| Abstract: | A novel di-hydrophilic beatine,N,N-bis3-(dimethylcarboxymethylammonio)-propyl] lauramide was synthesized using lauroyl chloride,tetramethyldipropylenetriamine and sodium chloroacetate as starting materials.The structure of this betaine surfactant was confirmed by FT-IR and ESI-MS spectrum,and surface chemical properties of the product were measured.The lowest surface tension is 36.04 mN/m,critical micelle concentration is 1.07×10-3 mol/L at 25 ℃.The foaming and emulsification properties and lime soap dispersing power of the surfactant were also studied. |
