用FT-IR法研究了水/辛烷基苯酚聚氧乙烯醚（Triton X-100）/正丁醇/环己烷组成的反相微乳液体系水池中存在的束缚、结合和自由3种不同的水的状态.分别考察了水与表面活性剂物质的量之比（Rw）、水油比φ（水与环己烷的质量比）、助剂正丁醇的含量对3种状态水含量的影响.发现在φ=2.8、m正丁醇/mTriton X-100=0.5、Rw=8时反相微乳液中出现自由水,形成水池;然后每个表面活性剂分子所含的结合水的数目稳定在2,束缚水和自由水的数目随Rw增加而增加;当Rw=20、m正丁醇/mTriton X-100=0.5时,φ从1增加到6.7的范围内,环己烷的多少对反相微乳液体系的红外光谱基本上没有影响;正丁醇与Triton X-100分子的烷基链、水分别发生作用,制约了自由水的出现.“,”The states of water in water/Triton X-100/n-butanol/cyclohexane reverse microemulsion,trapped water,bound water and free water,have been studied at various molar ratio of water to Triton X-100,mass ratio of water to oil（） and the content of n-butanol by means of Fourier transform infrared spectroscopy（FT-IR）.It was found that the water pools formed after Rw being larger than 8 as was 2.8 and mn-butanol/mTriton X-100 was 0.5;and the number of free water,the trapped water of per Triton X-100 molecule increased with Rw,while the number of the bounded water was almost constant at 2;the mass ratio of water to oil（1～6.7） had little effect on the FT-IR spectroscopy of the reverse microemulsion at Rw of 20 and mn-butanol/mTriton X-100 of 0.5.In addition,the n-butanol molecules interacted with both molecules of Triton X-100 and water,and it retarded the formation of free water.
