摘要： 近红外(NIR)光谱技术可用于表征氯仿体系中反胶团增溶水的能力. 对于C12-s-C12•2Br (s=2, 3, 4, 5, 6, 8)系列, 不论体系是否含有NaBr电解质, 由于具有较短联接链的表面活性剂易形成较大的反胶团, 其增溶水的能力随着联接链长度增加而降低. 与未含NaBr电解质的体系相比, 当体系中存在NaBr电解质时所形成的反胶团增溶水能力降低.

关键词: C12-s-C12•, 2Br, 反胶团增溶水能力, NIR光谱

Abstract: Near-infrared (NIR) spectroscopy technique can be used to characterize the ability of reverse micelles for solubilizing water in chloroform. For C12-s-C12•2Br (s=2, 3, 4, 5, 6, 8) homologue, no matter whether adding NaBr in water, the ability of the reverse micelles for solubilizing water reduces with increasing spacer length since the surfactant with shorter spacer trends to form larger reverse micelles. Compared with the system without NaBr, the ability of the reverse micelles for solubilizing water decreases when adding NaBr in water.

Key words: C12-s-C12•, 2Br, The ability of reverse micelles for solubilizing water, NIR spectroscopy
