SummaryA rapid thin-layer chromatographic method has been developed for comparing the different ethoxylation products during the manufacture of non-ionic surfactants. The ethoxylation products are separated on silica gel layers with ethyl acetate-acetone-water (12:5:0.5) as mobile phase. The chromatograms were visualized by exposure to iodine vapor for 3 min; densitometric scanning was then performed at 460 nm in reflectance mode and plates were evaluated by use ofRF values and peak-area data… Expand
