摘要:为了考察长脂肪链酰胺丙基磺基甜菜碱的性能,以硬脂酸甲酯、油酸甲酯、11-(3,4-二甲基-苯基)-硬脂酸
甲酯、3-二甲胺基丙胺、1,3-丙磺酸内酯为原料,通过两步反应合成了 3 种长脂肪链酰胺丙基磺基甜菜碱,并采

用 HNMR 及 MS 进行了结构确认。对样品进行了表面张力、耐温耐盐性、泡沫性能、油水界面张力性能测试,
发现 3 种长脂肪链酰胺丙基磺基甜菜碱均具有良好的表/界面活性、泡沫稳定性、乳化能力、耐盐性及耐温性;
长脂肪链中引入芳烷基增强了 11-(3,4-二甲基-苯基)-十八烷基酰胺丙基-N,N-二甲基磺基甜菜碱(C 18 DAMSB)的
表面活性,临界胶束浓度及表面张力分别为 1.57×10 –5 mol/L、28.89 mN/m,低于油酸酰胺丙基磺基甜菜碱
(UC 18 AMP3SB)及硬脂酸酰胺丙基磺基甜菜碱(R 18 DMSA);UC 18 AMP3SB 疏水链中的双键使其耐盐性优于
C 18 DAMSB 和 R 18 DMSA。

Abstract: In order to investigate the properties of long aliphatic chain amidopropylsulfobetaines, three long
aliphatic chain amidopropylsulfobetaines were prepared from methyl stearate, methyl oleate, 11-(3,4-dimethyl-
phenyl)-stearic acid methyl ester, 3-dimethylaminopropylamine and 1,3-propane sultone by two-step
1
reaction, then characterized, confirmed and evaluated by HNMR, mass spectrometry and measurements of
surface tension, temperature and salt resistance, foaming property, oil-water interfacial tension. It was found
that all three long aliphatic chain amidopropylsulfobetaines obtained exhibited good surface/interface
activity, foam stability, emulsification ability, as well as salt and temperature resistance. 11-(3,4-Dimethyl-
phenyl)-octadecylamidopropyl-N,N-dimethylsulfobetaine (C 18DAMSB) displayed enhanced surface activity
due to the introduction of aralkyl groups into long aliphatic chains with both the critical micelle concentration
–5
(1.57×10 mol/L) and surface tension (28.89 mN/m) lower than those of oleic acid amidopropylsulfobetaine
(UC 18AMP3SB) and stearic acid amidopropylsulfobetaine (R 18DMSA). Meanwhile, the double bond in the
hydrophobic chain of UC 18AMP3SB made its salt tolerance better than C 18DAMSB and R 18DMSA.
