| Abstract: | Summary Optimum conditions were obtained for the determination of low-molecular epoxides by a method based on derivatization with
picric acid and thin-layer chromatography on silica gel. The chromatograms were visualized with solutions of primary, secondary
or tertiary amines in acetone. Most of the monoepoxides gave only one spot; diepoxides gave two spots. The detection limits
for highly reactive epoxy compounds (derivatization time less than 2 hours) were estimated to be approx. 0.02 μmole. |
