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^(1)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(RDMSA);UC_(18)AMP3SB疏水链中的双键使其耐盐性优于C_(18)DAMSB和RDMSA。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-dimethylphenyl)-stearic acid methyl ester,3-dimethylaminopropylamine and 1,3-propane sultone by two-step reaction,then characterized,confirmed and evaluated by ^(1)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-Dimethylphenyl)-octadecylamidopropyl-N,N-dimethylsulfobetaine (C_(18)DAMSB) displayed enhanced surface activity due to the introduction of aralkyl groups into long aliphatic chains with both the critical micelle concentration(1.57×10^(-5)mol/L) and surface tension (28.89 mN/m) lower than those of oleic acid amidopropylsulfobetaine(UC_(18)AMP3SB) and stearic acid amidopropylsulfobetaine (RDMSA).Meanwhile,the double bond in the hydrophobic chain of UC_(18)AMP3SB made its salt tolerance better than C_(18)DAMSB and RDMSA.
