Detersive Performance of n-Undecane as Drycleaning Solvent and Application of Enzyme to Drycleaning System.

考察了以正十一烷为干洗剂的除垢效果，并与其他市售石油溶剂进行了比较。以氯化钠为水溶土，炭黑和三烯烃混合物为色土，讨论了表面活性剂在溶剂中增溶的水对土壤去除的影响。表面活性剂(气溶胶OT)在溶剂中的最大增溶量按斯托达德溶剂和氢化斯托达德溶剂-正十一烷和正十一烷的顺序递增。氯化钠的脱除速率随溶解水量的增加而增加。炭黑与三烯烃的混合脱色率随增溶水量的增加而降低。然而，在水与表面活性剂的摩尔比较低且恒定的情况下，去除速率保持在一定的水平上。用傅里叶变换红外光谱研究了气溶胶OT反胶束增溶水的特性。用高斯曲线拟合水羟基的宽峰。观察到了三种类型的水。

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.
