摘要：

Microemulsions stabilized by soybean lecithin and ethanol have been characterized with respect to phase behavior, distribution of the ethanol cosolvent, conductivities, viscosities, and volume fractions of the different phases in Winsor III systems. The conductivities and viscosities of the surfactant-rich phase in the Winsor III system indicate that this phase exhibits a bicontinuous structure. The reaction yield at 298.2 K for the enzymatic conversion of cholesterol to cholestenone by cholesterol oxidase performed in a Winsor III system containing water, lecithin, hexadecane, and ethanol is low.
