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
