摘要

棕榈脂肪酸馏分可用于生产脂肪醇硫酸盐。由此生成的 C16 脂肪酸十六烷基硫酸钠（SHS）克拉夫特点较高，限制了其应用。在此，我们建议使用与两性月桂酰胺丙基甜菜碱（LAPB）混合的 C16 硫酸盐。我们测定了 SHS 在 LAPB 中的溶解度，并根据其溶解度制备了两者的混合物。研究了表面活性剂混合物的界面特性。利用染料增溶法测定了表面活性剂混合物的 CMC。分析了混合物的性能特性，如发泡和粘度。结果表明，在 LAPB 中添加少量 SHS 也会导致其 CMC 发生显著变化，但 LAPB 的发泡和粘度性能保持不变。

The effect of addition of sodium hexadecyl sulfate on the performance properties of lauramidopropyl betaine

Palm fatty acid distillates can be used to produce fatty alcohol sulphates. The sodium hexadecyl sulphate (SHS) of the C16 fatty acid thus formed has a high Krafft point which limits its use in applications. Here we propose the use of C16 sulphate mixed with the amphoteric lauramidopropyl betaine (LAPB). The solubility of SHS in LAPB was determined and mixtures of the two were prepared to the extent of their solubility. The interfacial properties of the surfactant mixtures were investigated. The CMC of the surfactant mixtures was determined using dye solubilisation. The performance properties of the mixtures, such as foaming and viscosity, were analysed. It was concluded that the addition of even small amounts of SHS to LAPB causes a significant change in its CMC, although the performance properties of LAPB in terms of foaming and viscosity are maintained.
