Abstract
Structural analysis was studied for nonaromatic poly (oxyethylene) quaternary ammonium compounds.
It became possible to discriminate between mono and dialkyl types of these compounds by TLC with solvent systems consisting of hexane-chloroform-methanol-sodium perchlorate (10 : 10 : 10 : 0.05).
On the other hand, these compounds were converted to tertiary amines by hydroiodic acid cleavage and successive Hofmann degradation, and the amines were analyzed by GC with 10% apiezon grease L containing potassium hydroxide packed in a 0.25m column.
These amines were identified by IR, NMR, and MS spectra, and the relationships between original compounds and the types of these amines were clearified.
These two methods were used to structural analysis of these compounds in household detergents or toiletaries that were separated by ion exchanger.
