Soil removal n-undecane as drycleaning solvent was investigated in comparison with those of other commercially available petroleum solvents. The effects of the water solubilized in the solvents by surfactant on soil removal were also discussed by using sodium chloride as water soluble soil and mixture of carbon black and triolene as pigment soil.Maximum amount of the water solubilized in the solvents by the surfactant (Aerosol OT) increases in the order of Stoddard solvent< hydrogenated Stoddard solvent - n-undecane< n-decane. The removal rate of sodium chloride increases as the amount of the solubilized water increases. The removal rate of carbon black mixed with triolene decreases as the amount of the solubilized water increases. However, in case that the molar ratio of the water to the surfactant is low and constant, the removal rate is kept constant at the certain level. The characteristic properties of water solubilized by Aerosol OT reverse micelles was investigated by using FT-IR spectroscopy. The broad peaks obtained for water OH was resolved by Gaussian curve fitting. Three types of water was observed.

研究了正十一烷作为干洗溶剂的去污性能，并与其它市售石油溶剂进行了比较。以氯化钠为水溶性污垢，炭黑和三烯混合物为色素污垢，讨论了表面活性剂增溶于溶剂中的水对污垢去除的影响，结果表明，表面活性剂（AerosolOT）增溶于溶剂中的最大水量按Stoddard溶剂<氢化Stoddard溶剂-正十一烷<正癸烷的顺序增加。氯化钠的去除率随着溶解水量的增加而增加。随着增溶水量的增加，炭黑与三烯烃混合物的去除率降低。然而，在水与表面活性剂的摩尔比低且恒定的情况下，去除速率保持恒定在一定水平。用傅立叶变换红外光谱法研究了气溶胶OT反胶束增溶水的特征性质。通过高斯曲线拟合解析了水OH的宽峰。观察到三种类型的水。
