利用傅里叶变换拉曼光谱和傅里叶变换红外光谱对Ｈ２Ｏ／ＫＤＥＨＰ（７５％）－ＨＤＥＨＰ（２５％）／ｎ－ＨＥＰ－ＴＡＮＥ微乳体系的表面活性剂疏水链和极性头基与水分子的相互作用进行了研究。结果表明：当加水量由Ｗ０＝１增加至４３时，表面活性剂极性头基［ＰＯ２］－的反对称伸缩振动由１２３３ｃｍ－１移至１２０７ｃｍ－１，其对称伸缩振动由１０９４ｃｍ－１移至１０８９ｃｍ－１。表面活性剂疏水链的堆积结构也发生了变化，表现在拉曼光谱上为碳氢振动吸收峰的峰高比Ｉｒ（Ｉ２９６２／Ｉ２８７５），Ｉｒ（Ｉ２９３７／Ｉ２８７５），Ｉｒ（Ｉ２９１６／Ｉ２８７５）和Ｉｒ（Ｉ２９０３／Ｉ２８７５）随加水量增大而增大。结合二阶导数谱和傅里叶变换退卷积谱，本文还对ＫＤＥＨＰ和ＨＤＥＨＰ的存在状态进行了探讨，认为体系中表面活性剂分子有多种存在状态。
Hydrophobic chains and polar head groups of H2O / KDEHP (75%) - HDEHP (25%) / n-HEP-TANE microemulsion system were characterized by Fourier transform Raman spectroscopy and Fourier transform infrared spectroscopy The interaction of water molecules has been studied. The results show that the antisymmetric stretching vibration of surfactant polar head group [PO2] - moves from 1233cm-1 to 1207cm-1 when the amount of water increases from W0 = 1 to 43, and its symmetric stretching vibration shifts from 1094cm-1 To 1089 cm-1. The stacking structure of the hydrophobic chains of the surfactants also changed. The Raman spectra show that the peak height ratio of the absorption peak of hydrocarbon vibration is Ir (I2962 / I2875), Ir (I2937 / I2875), Ir (I2916 / I2875) Ir (I2903 / I2875) increases with increasing water. Combined with the second derivative spectrum and the Fourier transform deconvolution spectrum, the existence of KDEHP and HDEHP was also discussed in this paper. It is considered that there are many existing states of the surfactant molecules in the system.
