【摘要】 测定了不同含水量的丁二酸双（２－乙基已基）酯磺酸钠（ＡＯＴ）反胶束溶液的核磁共振谱及红外光谱，以探测水在反胶束中的结构和性质。研究表明，在ＡＯＴ反胶束中，Ｎａ￣＋水化层内的水分子由于强烈的离子－偶极相互作用而被紧紧束缚，使水分子间的氢键缔合大为削弱；当引入更多的水时，水分子的束缚程度大幅度下降，氢键缔合大为增强。但即使在最大的反胶束中，水的流动性仍比普通水低。反胶束中水的这些特殊性质正是反胶束溶液获得广泛应用的内在依据。更多还原

【Abstract】 In order to detect the structure and properties of water in reverse micelles,the spectra of NMR and IR of AOT rcverse micellar solutions with different water contents were recorded.It is shown that water molecules situated in the first hydrated layer of Na￣+ ion of AOT reverse micelles are tightly bounded while the hydrogen-bonded association between them is greatly weakened due to the strong interaction of ion-dipole.As more water is introduced,the bounded degree of water decreases while the hydrogen-bonded association is enhanced.Even in the largest reverse micelles,the mobility of water in reverse micelles is still lower than that in bulk.It is for these peculiar properties of reverse micellar water that reverse micellar solution has come into wide use.更多还原
