Abstract
Capillary supercritical fluid chromatographic methods were developed for the separation and quantitation of oligomers of propoxylated glycerols and fatty acid-esterified propoxylated glycerols. Samples containing mole ratios (propylene oxide to glycerol) of 5, 8 and 14 were chromatographed. Separations depended primarily upon the molecular weight or the number of the propylene oxide units. The oligomer distributions in the propoxylated glycerol and the oleic acid-esterified propoxylated glycerol samples were determined.
