title: Sucrose Derivative Surfactants Studied by Inverse Gas Chromatography.
abstract: Specific retention volumes of 12 solvents were measured at different temperatures on columns containing sucrose monopalmitate as their stationary phase. The influences of the temperature, adsorption effect in interface gas-liquid, and carrier gas flow on the chromatographic retention were analyzed. Henry's constants were calculated and the solubilities in the surfactant were obtained. The results were analyzed by the combination of Flory-Huggins and Hildebrand theories, and the solubility parameter of surfactant was obtained at different temperatures. The relation between solubility parameter and hydrophile-lipophile balance was discussed. Copyright 2001 Academic Press.
