摘要:以三乙醇胺、长链脂肪酸为原料,制得脂肪酸三乙醇胺单酯(FTME),再经磺化反应合成了 4 种脂肪酸
三乙醇胺单酯琥珀酸酯磺酸盐(FTMS)两性表面活性剂,以月桂酸、棕榈酸、硬脂酸、油酸为脂肪酸合成的
FTMS 分别命名为 FTMS-1、FTMS-2、FTMS-3、FTMS-4。分别用碱性亚甲基蓝法和酸性溴酚蓝法验证了产物
的离子性,并考察了 FTMS 结构中的烷基链长度及其不饱和度对表面张力、Krafft 点、样品液粒径及粒径分布、
乳化能力的影响。结果表明:产物显示出两性离子的特征,随着脂肪链碳数增加,其 Krafft 点升高,平均粒径
逐渐增大,但脂肪链中的不饱和双键有助于 Krafft 点的降低和粒径的减小。FTMS-1 和 FTMS-4 具有优异的表面
活性。其中,FTMS-1 的临界胶束质量浓度(CMC)为 52.97 mg/L,表面张力 γ CMC 为 36.1 mN/m,其乳化能力
与脂肪醇聚氧乙烯醚(AEO-9)相当且优于十二烷基磺酸钠。

Abstract: Fatty acid triethanolamine monoester (FTME) was synthesized from fatty acid and triethanolamine.
Subsequently, four kinds of fatty acid triethanolamine monoester sulfosuccinate (FTMS) surfactants were
obtained by esterification of FTME with maleic anhydride and then sulfonation with sodium sulfite,
wherein, the FTMS products synthesized by laurate, palmitate, stearic acid and oleic acid were named as
FTMS-1, FTMS-2, FTMS-3 and FTMS-4, respectively. The ionicity of the products were verified by
alkaline methylene blue and acid bromophenol blue. The effects of alkyl chain length and unsaturation of
products on the surface tension, Krafft point, particle size, particle size distribution and emulsifying ability
were investigated. The results showed that the amphoteric products were successfully obtained. Krafft point
and average particle size increased with the increase of alkyl chain length, however, the unsaturation in
alkyl chain was conducive to the decrease of Krafft point and average particle size. Especially, FTMS-1 and
FTMS-4 exhibited excellent surfactivity. The critical micelle concentration (CMC) of FTMS-1 was
52.97 mg/L, and the surface tension at CMC (γ CMC) reached 36.1 mN/m. The emulsifying ability of
FTMS-1 was equivalent to that of AEO-9 and superior to that of sodium dodecyl sulfate.
